Unable to send messages in the night

I am unable to send messages after 8:45 PM at night or before 9 AM in the morning. Why?

By default, you are configured a promotional account. As per TRAI regulations, promotional SMS can be delivered only from 9am to 9pm.

Transactional messages such as OTPs and order updates can be delivered 24x7. If you would like to send transactional SMS, contact your account manager or email us at to change your account to a transactional account. Please check if your messages can be qualified as transactional SMS here.

If your business SMS requirements need both promotional and transactional accounts, we can configure both the accounts free of cost for you.

Unable to send messages to DND numbers

I get an error ‘Blocked by DND filter’ when I try to send a message to my number. My messages are also not being delivered to some of my other contacts. How can I send messages to all the numbers, including the ones in DND category?

By default, you are configured a promotional account. As per TRAI regulations, promotional SMS cannot be delivered to numbers registered in the National Do-Not-Disturb (NDND) registry. Fastsms India ensures you comply with TRAI regulations and automatically scrubs all the DND numbers from your recipients. You will not be charged any SMS credits for these numbers. You can check if a number is registered in DND here.

  • If you would like to send promotional SMS to your contacts with DND numbers, please ask them to explicitly opt-in via myDND manager.
  • Transactional messages such as OTPs and order alerts can be sent to all numbers, including the ones registered in DND. If your messages are transactional in nature, contact your account manager or email us at to change your account to a transactional account. Please check if your messages can be qualified as transactional SMS here.

 If your business SMS requirements need both promotional and transactional accounts, we can configure both the accounts free of cost for you.

Test messages are getting delivered with a delay

I just signed up with Fastsms India and sent a few test messages. It took almost 3-4 minutes to deliver some of the messages. How can I get better delivery speeds?

Fastsms India provides best-in-class SMS delivery for both transactional SMS and promotional bulk SMS, thanks to our platinum operator connectivity. However, we manually monitor your first few messages for spam and this will likely result in a small delay. Our team continuously monitors your account activity and after a few checks, automatically removes this manual monitoring to ensure your messages are delivered instantly.

 If you would still like to test the delivery speed, we can temporarily remove manual moderation for your account. Please contact us at

Unable to send message to my own number

My number is registered in DND. But I still get many messages from my bank, online shopping websites, restaurants etc. Then why cannot I send message from Fastsms India to my own mobile number?

By default, you are configured a promotional account. As per TRAI regulations, promotional SMS cannot be delivered to numbers registered in the National Do-Not-Disturb (NDND) registry. 

You can send messages to DND numbers only if your account is transactional and the recipient of those messages is registered to your company/services and has opted in to receive SMS from you – just like you are registered to your bank or online shopping website where you have provided your contact details and agreed to their terms.

Error Code 3: Invalid Login while using Fastsms India API

When I try to send SMS using Fastsms India API, I receive an error message saying Error code 3: Invalid login. What am I doing wrong?

Error code 3: Invalid login is thrown when one of your login parameters is incorrect. The login parameters include ‘username’ and hash or apikey. Here are a few quick checkpoints to identify the problem:

  • Incorrect URL? Please make sure you call .
  • Incorrect ‘username’? Please check if you correctly entered your registered email ID of Fastsms India in the ‘username’ field.
  • Incorrect ‘hash’? Every account will have a unique hash key. Your hash key will be available in your messenger under Help -> All Documentation -> Your hash key. Please ensure you entered this hash key accurately in the ‘hash’ parameter. Note that your hash key changes whenever your password changes. At the time of password change, stop your API calls, update your hash key once the change is done and then, restart the API calls.
  • Incorrect apikey? You can generate your API keys from Settings -> All Settings -> API keys. API keys can be restricted to a set of IP address. The API key entered in apikey parameter should match one of the active API keys in your list and if that particular API key is restricted to a set of IPs, your machine/server/system IP should be in the IP set.
  • If the Fastsms India API has been called multiple times with incorrect credentials, your account will be temporarily blocked to prevent any malicious exploitation. Please contact the support team to unblock your account.

Error code 80: Invalid Template while using Fastsms India API

I converted my account to Transactional and now, when I try to send an SMS using Fastsms India API, I receive an error Error code 80: Invalid Template. How can I correct it?

From a transactional account, you can send only those messages that match one of your pre-approved templates. Please ensure that your messages match one of the approved template formats.

If you would like to add a new template to suit your SMS content, login to your account, select Send -> Templates & Drafts and submit it for review. Once your template is approved, you can start sending messages based on that template. Get detailed information on how to add templates and send messages via API.

Messages not getting delivered with the desired sender name

I want my messages to be delivered with my company name as the header. How can I set this in my Fastsms India Messenger account? 


I want my messages to be delivered with my company name as the header. But, when I mention my company name as the sender parameter in Fastsms India API, the API response is “Error code 43: Invalid sender name”. What am I doing wrong?

By default, you are configured a promotional account. As per TRAI regulations, promotional SMS will delivered with a random 6-digit Sender ID assigned by the operator.

Transactional messages such as OTPs and order updates can be delivered with a 6-alpha character Sender ID of your choice. If you would like to send transactional SMS, contact your account manager or email us at to change your account to a transactional account. Please check if your messages can be qualified as transactional SMS here.

For Fastsms India control panel users:

The option to choose and assign a Sender ID will be available on the Send screen once your account is upgraded to a transactional account.

For Fastsms India API users:

This is an error response when incorrect value is passed on to sender parameter.

  • If your account is promotional, please ensure the sender parameter is mentioned only as TXTLCL – this will be changed to the random 6-digit Sender ID at the time of delivery. Changing this will lead to an error response.
  • If your account has been converted to transactional, you can use one of the pre-approved sender IDs which are already added in your account.

Unable to upload excel file while adding contacts

When I upload an excel file to a contact group in Messenger, I receive an error – ‘Nothing has been imported. Either there is no new data to import, or you have selected the wrong column headings.’ Where am I going wrong?

This error might be observed due to one of the following reasons:


  • Special characters or spaces in the mobile numbers column. Please clean the data and try uploading again.
  • If your excel file has additional merge fields (i.e. custom parameters along with mobile numbers), there might be a problem with the column headings. Ensure that the column with mobile numbers is correctly assigned the number field.
  • If your excel file has column headings, please uncheck the header name from Fastsms India Messenger before clicking on import button.

 If the error still persists, reach out to us at


Frequently getting logged out from Fastsms India messenger

I am getting logged out of my Fastsms India account quite frequently and so, unable to use the account. What’s happening?

This issue occurs whenever your login session IP changes. For security reasons, Fastsms India does not allow multiple IPs to access one account in a single session. Hence, the frequent log-out issue. Here’s what you should do: 

  • Allot a static IP to the Fastsms India Messenger domain – control.Fastsms
  • Alternatively, if your workplace ISP uses dynamic IP structure, ask your IT team to load-balance a single IP to the Fastsms India Messenger domain IP ( per session.

General Questions

What is SMS?

SMS stands for Short Message Service, and refers to the sending of short text messages from one device to another; in most cases from one mobile phone to another. The size of an SMS text message is restricted to 160 characters.

What is a Multipart / Concatenated SMS?

A standard text message is 160 characters long. If your message exceeds the limit, an alert is shown on the screen allowing to continue typing the message beyond the character limit. This message will count for 2 or more SMS Credits (depending on the length of your message) and you will be charged correspondingly. Special such as ~, ^, {, }, [, ], |, will constitute two characters.

Messenger allows you to send longer SMS of upto 765 characters which are split into smaller SMS and later joined at the receiving end which is a mobile. In this scenario, SMS length is calculated for 153 characters as 7 characters are used to concatenate the message when it is delivered to the handset.

What is an SMS gateway?

An SMS gateway is the means through which a computer can send or receive SMS messages. Often allowing for the conversion and sending of other forms of media or message (such as email), SMS gateways will generally utilise the same mobile phone networks as the messages sent from mobile phones.

Are there any contracts or commitments with Messenger?

There are no contracts involved in running a Messenger account - it all works on a pay as you go basis, so you can send text messages with no hassle. If you purchase any inbound systems they have a minimum term of one month which is renewable.

Who can use Fastsms India services?

Any Indian business, society or community group can use Text Local to reach out to customers, staff or friends with SMS, instantly connecting to people where ever they are. With different levels of service, there's something to suit an organisation regardless of size.

How long does the service take to set up?

Your SMS marketing campaigns can be up and running within minutes.

Do I need a mobile phone?

You do not need a mobile phone to use messenger; messages are sent and received from Messenger. It is all web based so you do not need to download anything. All you need is an internet enabled PC, Mac or Tablet.

Can I purchase credits online in Fastsms India? If yes, how?

Yes, you can purchase credits online in Fastsms India. Please follow the steps listed below:

  1. Log in to your messenger
  2. Click on the Buy option available in the top right hand corner.
  3. This will take you to the Order page
  4. Select your desired SMS bundle from the drop down option and fill in the details.
  5. Click on Order Credits
  6. You will be redirected to our payment portal powered by CCavenue
  7. Choose the payment mode and complete the payment process
  8. The credits will be added into your account instantly.

How can I send and receive SMS messages online?

It's essentially the same process that you would go through when sending a standard SMS message on your phone, only on your computer. With a Fastsms India Messenger account for you or your business, it's as simple as typing in your message, selecting the number you wish to send to, and pressing send. Job done.

How much does it cost to send a message?

The cost depends on how many credits you want to buy; one credit equals one text message and the credits last indefinitely. The cost of our credit bundles can be found on our prices page.

Will my credits expire?

Your credits will never expire.

How many characters can I send in a message?

You can send up to 765 characters in a message. Here, we refer to standard Latin symbols (ASCII) and not special or Unicode characters. Messenger displays clearly when composing your message as to how many characters you have used and how many credits your text will use up so you can edit the message accordingly.

What is length of an SMS and what is the relation between message length and credits?

The standard length of SMS is 160 characters in Latin symbols (ASCII). It also varies depending on the message type, especially if it is a Unicode message or if the message uses any special characters (refer to the question below).

A message with up to 160 characters uses up one SMS credit. If the message is more than 160 characters, one credit is used up for 153 characters as the remaining 7 characters are used to concatenate the message when it is delivered to the handset. So, one SMS credit is used up for a maximum of 160 characters, 2 credits are used up for 161-306 characters (=153*2) and so on. You can send messages up to 765 characters and this long message will use up five SMS credits (765 = 153*5).

How long does it take for Fastsms India team to convert my account to Transactional?

Once you upload all the required documents duly signed, Fastsms India support team will convert your account to transactional within 12 business hours. As soon as your account is converted, you will receive a notification over email from our support team.

I have uploaded the Transactional documents in the messenger. Do I need to send the hard copies as well?

Yes. Although we'll convert your account to transactional on receiving the soft copies, hard copies are mandatory for continuation of transactional services. You will have to courier the original hardcopy to the address mentioned below so as to reach us within 15 days of converting your account. To ensure that, we request you to share the consignment number of your courier via email

Can I have more than one sender ID approved for my transactional account? Are there any additional charges?

You can have multiple sender IDs approved in your transactional account and there is no additional charge for this. We only need a signed consent letter printed on your company letterhead clearly mentioning the sender ID to get it approved from the operator.

I have received a confirmation from Fastsms India support team that my account has been converted to transactional. What should I do next?

Once your account has been converted to transactional – the first thing you need to do is create your SMS templates. Once you add your template, our support team will check the content and approve the template. Remember transactional route is template restricted, hence you will only be allowed to send messages which match your approved templates. To know more about how to create templates, please refer our Step-by-step template guide.

How long does it take for the Fastsms India support team to approve the templates?

Templates are approved within 2 business hours during Monday – Saturday (9 AM – 6 PM) except on national holidays and major festivals. Having said that, if you need your templates to be approved urgently – you can always mail us at

I have a transactional account with Fastsms India. Now I want to do promotional campaigns for my product launch. Do I have to create a new account and purchase credits again?

No, you don’t have to purchase credits again for promotional messaging. We can create a promotional sub-account for you with one shared credit pool. So essentially it will be a separate account but you can transfer the credits from your existing transactional account only. To set this service up, we need one additional email ID which will be the registered username of your new account. There is NO additional cost involved in this whole process.

Can I send SMS in Regional Languages?

Yes, Fastsms India supports Unicode messages which will enable you to send SMS in Indian languages. Our transliteration tool will help you easily and quickly draft texts in local languages. On messenger we support most of the popular languages in India which include: Assamese, Bengali, Bodo, Dogri, Gujarati, Hindi, Kannada, Konkani, Maithili, Malayalam, Manipuri, Marathi, Nepali, Oriya, Punjabi, Sanskrit, Santali, Sindhi, Tamil, Telugu

What is a Unicode message and why is it used?

Standard SMS sent using the GSM 3.38 Character set allows the sending of 160 characters for a single message, and multiples of 153 for longer messages. The character set only allows those characters to be sent, and anything outside of it is changed – for instance í (that’s i-acute) gets changed to an i.

>Unicode allows the support of a much wider character set, and actually includes pretty much every character in the world, including Indian languages, some of the stranger European characters (like í), all the Cyrillic alphabets (e.g. Arabic, Russia, Punjabi and Greek), all the Asian ones (Chinese, Japanese etc), and also some of the emoticons out there! Basically, every single character you can think of.

An example Hindi Unicode message is: अब टेक्स्टलोकल से आप अपनी भाषा में आसानी से सन्देश भेज सकते हैं!

What are the differences between Unicode and GSM?

Firstly, the standard length of a Unicode message is 70 characters (compared to 160 for GSM). Long messages are supported for Unicode messages as well, and they are in multiples of 64 (compared to 153 for GSM). So a double length Unicode message can be up to 134 characters, triple 198, quadruple 262, etc.

Messages are priced the same way i.e., 1 credit is used up for 1 message (up to 70 Unicode characters), 2 credits are used up for double-length Unicode message (up to 134 characters) and so on.

Why are my messages using up two credits?

A message will use over one credit if you do either of the following:


  • You are using over 160 characters per message.
  • You are using over 70 characters in a Unicode message
  • You have merged data into your message which is increasing the characters.
  • I have sent a message to some numbers. How do I check if the message has been delivered?

    Fastsms India provides real time delivery reports of the messages sent. You can access the status of each message in the Reports section in messenger. The report is further divided by channels (Group message, single message, API, email 2 SMS). Depending on the channel used to send messages, you can check the reports in the respective section. Here is a quick reference of the report status and few possible reasons.

  • Status Description
    Delivered Message is delivered
    Expired Out of coverage area, Switched off, Insufficient Memory, Tower station Failure, No routing info available from HLR
    Undelivered  Absent Subscriber, Memory Capacity Exceeded, Mobile Equipment Error, Network Error, Barring, NDNC Failed
    Pushed Pending at the operator's end (out of coverage area, inbox is full, handset is switched off…)

Does Fastsms India provide data?

We do not provide data, however we do offer short codes and long codes which are extremely effective in collecting opt-in numbers from your customers and can be used alongside any text marketing activity.

How secure is my data?

Your data is completely safe. Fastsms India does not share or pass on any of your data, including the mobile numbers you upload. Your data will only be used for your SMS marketing. For further information see our SLA. Fastsms India provide a secure 128-bit encrypted service which is equivalent to online banking security.

Can I merge data into my messages?

Yes, you can merge data into your messages by inputting the information into your excel spread sheet. Once you have uploaded the file you can make sure each column heading is relevant to the information stored in each column.

How to send a message to all the contacts in my mobile phone through Fastsms India mobile app?

You can import your contacts easily to your contact groups. Here is what you need to do:

  1. Login to our mobile app
  2. Go to Your contact groups
  3. From the tools section click on import from phone
  4. Select the group and then select all your mobile contacts
  5. Click on Next and all the selected contacts will be imported to that particular group.

What is an API hash key? Where do I find my API hash?

API Hash key is the encrypted form of your password. This is unique for every user in Fastsms India. You will need to pass the correct hash key to integrate your application with our API.

The unique API key for your account will be available in the messenger under Help->All Documentation -> Your hash key

Note: Changing password will change your hash key. So do not forget to update the new hash key in your API code.

I am having a reseller whitelabelled account with Fastsms India. Where do I find the API hash keys for my sub accounts?

Since you are a whitelabelled reseller, your sub accounts will not have the help section to check their API hash. However you can check the unique hash keys for all your users from Settings -> Reseller Settings -> User Accounts.

Can I send messages outside India?

You cannot send messages to mobile numbers registered outside India.

However, messages can still be delivered to mobile numbers registered in India, even when the subscriber is on international roaming.

Can people text in to my Short Code from outside India?

Only subscribers registered with Indian mobile networks can send texts to Indian short codes.

Our Dedicated Inbound Numbers (DINs or long codes), however, can receive texts from any mobile numbers – Indian or international. The cost to the sender will be their standard network rate.

Can people text in to my long code from outside India?

Subscribers registered on any network (international or Indian) can text in to a DIN / long code, since a DIN / long code uses the country code.

However, a short code is local to the country in which it is issued and only phones registered within that country’s network can text into it.

How are my customers charged for texting in to my short codes and long codes?

In India, a premium rate of Rs. 3 is charged for texting in to a short code and its extensions.

Texting in to a long code is treated as a standard P2P SMS and the end customer is charged as per her SMS plan.

Why do numbers look like 4.47741E+12 when I export to Excel?

This is because Excel thinks your mobile number is a long number so has converted it into scientific notation. To fix this click on the column header, click Format Cells->As Number->0 decimal places.

How long do messages stay in my inbox for?

Inbound messages are stored forever in your Fastsms India Messenger account. You can easily export these to an excel file for your own records.

Can the sender name be my business name, rather than a random number?

Yes. If you have a transactional account, you can request for a Sender ID of your choice at no extra cost. The Sender ID must be 6 character long with all Latin alphabets. Sender IDs are a great way to enhance awareness of your business and conduct professional communication.

Promotional messages are sent from a 6-character long, numeric Sender ID that’s randomly generated and assigned by telecom operators.

How can customers reply to my messages?

Your customers cannot directly reply to your Promotional/Transactional SMS as they are sent from a Sender ID. However, you can embed your inbox information (Keyword + short code / long code) in your messages and your customers can use these to reach out to you.

Can I schedule messages to be sent at a later date?

Yes, it's easy to queue text messages for delivery. Choose to schedule them to be sent only after specific times and dates. You can also set an end date for your message to expire, to prevent it from being sent out after a specified date. Staggering messages is also possible; to allow time to handle responses instead of being overwhelmed by many all in one go. If you need to change the time and date of the scheduled SMS, you can do so via the reports section of Messenger.

What business sectors can benefit from mobile marketing?

SMS is a universal tool. Whether being used purely for sales and marketing or for transactional alerts, SMS can fit into any application and sector. Please refer to our case studies for more information.

Does the size of my business affect the success of SMS?

No, smaller campaigns work as well as the larger campaigns, as long as you have an opt-in database of your contacts and you send relevant messaging to them.

How can local businesses get greater benefits from text marketing?

Local businesses can benefit from being able to instantly communicate to hundreds or thousands of people about your latest offers & promotions. Messages are instantly delivered typically within 5 seconds and read by 95% of those customers within the first 5 seconds. That’s guaranteed communication within 10 seconds of sending a message!

SMS Attachments

What is an attachment?

An attachment is an additional file you can send as a link in a text message.


How do I attach a document to an SMS message?

Within the Messenger interface, select the file that you wish to attach in the same way that you would when composing an email. Messenger will convert the file into an easily accessible link within the body of the text message. The file will be hosted securely on our servers. If the document that you wish to attach is smaller than 10MB in file size, you're good to go. So attaching a file to an SMS message is not only easy, but requires zero IT infrastructure on your end.

When on the Send SMS screen, click to include attachment and we will host it online for you and add the short link in your text message.

How much does it cost to send an attachment?

There is no extra cost to include in attachment to your text message

Tickets, Vouchers, Loyalty cards

What is the difference between a voucher, a ticket and a loyalty card?

Tickets and vouchers are for one time use only. Once the unique code has been redeemed, it cannot be redeemed again.

A loyalty card can be used multiple times; you set the rules for how many times it can be redeemed and what actions sit behind each scan.

My business doesnt have a need to offer tickets is there anything else that I can use this feature for?

Yes, these are unique codes that can be used for any kind of redemption. A unique code or bar code could be used for entry into an event or venue, to claim a discount on a purchase, one-time access to an online account or a unique pin number.

What will my mobile voucher, ticket or loyalty card look like?

You design this as part of the tool in your Messenger account. Its a mobile optimised page, you add images or logo's, colours, text, bar codes and/ or QR codes, plus any links or mail merge features.

How do I send it to my customers?

Your voucher, ticket or loyalty card is sent to your customers as a link in a text message. This can be sent directly to them or as an auto response to a short code keyword.

Do I have to create my own unique codes?

Messenger can assign unique codes to all your customers or you can upload your own unique codes if you have them.

How do my customers redeem their code?

Codes can be redeemed by either scanning the bar code or QR codes with the Fastsms India app which will marry up with the rules set in place in your Messenger account, or you can manually enter the code into your Messenger account or integrate it with your EPoS system.

What is Passbook?

Passbook is a built in app on all iPhones, while PassWallet is the Android alternative. It saves all mobile tickets, boarding passes, vouchers and card in one place. You can include a Passbook/ PassWallet feature in every ticket, voucher or loyalty card you create.

Do I have to include Passbook?

It's optional, but costs no extra and gives your contacts an additional way to redeem their ticket voucher or loyalty card.

What if my customers dont have a smart phone?

You can include the unique code for that contact in the body of the text message so they can still access the code even if they cant click through to a mobile page. You don't have to include a mobile page.

Can I integrate this with my epos/online store?

Yes, full integration is possible so tickets, vouchers and loyalty cards can be redeemed through your till system.

Will I be able to access results of who has and hasn't redeemed?

Yes, all results are displayed in your reports and you can also download them as a CSV file. You can separately download the data for anyone who hasn't redeemed their code yet and target them with a reminder text message.

Can I include anything else in my mobile ticket/voucher/loyalty card?

You can include any normal mail merge fields and trackable links in the text message itself or on the mobile ticket, voucher or loyalty card.

Do I set the rules for my loyalty card?

Yes, you set how many times it can be redeemed and what alerts are set after each scan, so you know what rewards are due and when.

Are the unique codes open to abuse? Can they be used more than once?

The unique codes we set for one time use are fool proof and cannot be redeemed more than once. If attempted, an error message will occur and then redemption will be declined.

My business runs offers for short periods of time, can I put a start and end date on the vouchers I send out?

Yes, you can set the expiry date and an expiry message on the first set up screen. Once you've completed the entire set up you choose when you want to push the ticket, voucher or loyalty card live.

Receiving SMS

Can I receive replies?

Yes you can. You can use your free inbox to receive replies, or setup a new inbox by purchasing a reply number of your choice. A reply number is categorized by the length of the reply number which may be a short code (reply numbers with 6 to 9 digit number extensions on 56263) or a 10 digit virtual mobile number (VMN / DIN). You may setup as many keyword – inboxes as you wish with dedicated reply numbers, where as a shared reply number allows you to setup one inbox on the keyword you have choosen.

How can I receive text messages online?

Using an inbound text number or short code, you can receive text messages from your customers at no extra cost. It's free for you to receive the message and only costs the customer their standard network cost. All messages will appear in your Messenger account, so simply log in and view at your leisure. You can also choose to automatically forward all inbound messages to you via email for free.

Short codes will only work from handsets registered in the same country as the code, as there is no country code on the number. Our 56263 short code and its extensions work only in India. There are additional options to personalise keywords and Short Codes For more info on Short Codes, see the page on receiving SMS


How do I see my received messages?

All the messages you receive online will appear in your Fastsms India Messenger inbox. This inbox works just like your email inbox.

What is the cost of receiving replies?

It costs you absolutely nothing to receive a reply however the sender will be charged at their standard network rate.

What is a keyword?

A keyword is a requirement when using any kind of shared number. The message must start with the keyword so the Fastsms India system can direct the message to relevant person's inbox. Try and keep your keyword as simple as possible to avoid mistakes.

What is a mobile marketing short code?

A short code is essentially an abbreviated phone number, and in the context of mobile marketing, these allow for consumers who have received a marketing message to easily respond. As well as allowing for easier responses from consumers, the short code system often makes it much easier for an automated mobile marketing programme, like ours, to handle the consumer's reply.

For example, if you were looking to increase the number of recipients of your marketing messages, you could send out a group email with the message “To opt-in to receive further marketing communications send 'OPT-IN' to 00000”. In this instance, '00000' is the short code number, which would direct the message to our servers. Upon reading the keyword 'OPT-IN', our software will automatically sort the number that sent the message into your business' opt-in database. This is just one example of the utility of short codes in mobile marketing, but it succinctly illustrates their potential.

Fastsms India owns the short codes 56263 and all its extensions in India.

Does a Dedicated Inbound Number need a keyword?

No one other than you uses your Dedicated Inbound Number so no keyword is required, although you can create keywords within your Messenger for various SMS marketing campaigns if you wish.

Can I receive text messages as an email?

All inbound message sent to Messenger will be automatically forwarded to you via email. You can select up to 20 email addresses for the messages to be forwarded to for each live inbox. This is free.

Can you forward a message I receive to my number?

Of course, we can automatically forward inbound messages to your handset. This costs 1 message credit.
