SMS Sending Options

We currently offer multiple options for sending and receiving SMS', they are Email-To-SMS, via the Platform and through our Rest API. All solutions will be provisioned across all accounts, provided you have a signed and executed SMS agreement. If you are not currently setup for SMS but are interested in the product, feel free to get in touch with our sales team who will be happy to assist with setting up a trial account for you. *

Email To SMS

Email to SMS is one of the simplest to rollout and use throughout your business, by default your email domain '@DOMAIN.com.au' will be whitelisted for sending SMS' using our platform, all that is needed to send is for an email to be sent to 'NUMBER@smstransmit.com'. For example, to send an SMS to 0400123456, send an email to '0400123456@smstransmit.com', this can be in E.164 format as well e.g. +61400123456@smstransmit.com.

You can send the SMS to multiple mobile phones by simply adding more recipients to the To or CC fields in your email.
Note that there is a limit of 100 recipients per email. To get the best experience sending SMS over email:
  • Delete your email signature before sending. All text that is in your email will be sent over SMS.
  • Because SMS does not support formatting, we will convert your email to plain text. As such, any formatting such as bold, italics and different font sizes will be removed and simply the text will remain.
  • If you wish only certain email addresses to be whitelisted for sending or if you wish to allow access for other domains to send this can be done, please contact the support team with regards to changing your Email-To-SMS configuration.

Receiving Replies

If your Email-To-SMS service is configured for two-way messaging, you can receive replies to your SMS via email, this is enabled by default.

Replies will be sent to the email address that last sent an SMS to the mobile that is replying.  If enabled, replies via email will contain the full conversation history just like a normal email.

When you receive a reply, you can reply to the email just like a normal email to continue the Email-To-SMS conversation.  In all major email clients, our system will remove the conversation history when you reply, so just your response and not the entire conversation history is sent back via SMS.

Did You Know?

If you are having a conversation over Email-To-SMS, you can forward the conversation to somebody else in your organization (who is registered for Email-To-SMS) to continue the conversation.  Replies will be sent back to the last email address to reply to the SMS.

If you have a dedicated number, you can publish your dedicated number and two-way Email-To-SMS conversations can be initiated by sending an SMS to the dedicated number.  The email address these are sent to by default is configured against the dedicated number.

Dedicated Numbers

Dedicated numbers can be purchased against your account.  Dedicated numbers have specific webhook call back URI options which are configured against the dedicated number.  When using a dedicated number to send SMS, all responses must be routed back to the same webhook call back URI.

When using dedicated numbers, if you need multiple webhook call back URIs for your use case, you must purchase multiple dedicated numbers and configure each with a different call back URI.

When using dedicated numbers, you can specify the delivery receipt call back URI when making the API call.  This gives you the capability to set message-specific delivery receipt call back URIs per message.  If the delivery receipt call back URI is not set, the default delivery receipt call back URI will be used that is defined against the dedicated number.  If no delivery receipt call back URI options are set, no call back will be made to your system.

SMS Platform

The SMS platform is on par with Email-To-SMS in terms of ease of use and also has some handy features  which we will go through as well, in order to access the SMS platform you will need a login to the platform, if you don't have a login or aren't sure if you have one please contact the support team who can check and reset passwords as required.

Once logged in, you will want to click into 'SMS Marketing' and then you will be given the options between 'Sent' and 'Received', these are pretty self explanatory but there is a bit more to the send side that needs to be explained in a little more detail.




Sending SMS via the Platform

In order to send SMS' you will need to click 'New SMS' in the top right, you will then be taken to a new screen and given the two types of SMS send out, via single SMS or via a bulk send out.

You can send out from three options, Leased Number, Alphanumeric, Mobile number.

Leased Number will select a number from our pool of dynamic mobile numbers, this option allows for two-way SMS

Alphanumeric allows a word or specific number to be sent from, if a word is used SMS can only be sent and not received back, if a specific mobile number is used replies will be sent to the appropriate mobile device. Alphanumeric words can only be 11 characters in length and does not allow special characters.

Mobile Number utilizes dedicated mobile number assigned to your account, these number are only assigned upon request.

Single SMS

To send a single SMS all that is required is to put your required destination into the 'To' column and for your relevant message to be put into the 'Message' section as shown below:



Rest API 

For larger enterprise services who wish to interact directly with us the API will be the best tool for you, with complete flexibility the API will allow you to utilize all functionality of our SMS service granting full access to customization options via optional parameters. For more information please contact 1300 00 1300.

Bulk SMS Sending

We offer a bulk sending option in the platform for when you have a message that needs to be blasted out to many recipients at once.

Bulk Sending Option

To do this, all you need to do it upload a csv of the number data, there are some things to note when doing this:

1. Maximum of 2000 numbers per request, if you need to sent to more, split out your spreadsheets.

2. Numbers must be presented in '614XXXXXXXX', any 04 numbers, blank numbers, or numbers missing digits will cause the upload to fail.

3. Column Header name (Phone Number) must be correct or the upload will fail.

4. The message to every number must be the same.


Attached is the example CSV but this is also available in the platform.


Sending is almost identical to sending a normal SMS, all you need to do is upload your spreadsheet, type your message, select the From Number (if applicable) and hit send.

Tips: Add in your own mobile number at the end of the sheet to know when all recipients should have received a message. (delivery times vary dependent on mobile network, but will show message has been processed through our system).

SMS Segmentation

SMS's can be segmented if they are too long or use non-standard characters, messages are charged on a per segment basis and not per message. Customers can be frequently charged for many segments if they use non-standard characters.

For GSM-7: 1 Message to 1 x recipient: 1 - 160 characters

For joined segmented Messages to 1 x recipient:

  • 1 – 153 characters = 1 Message
  • 154 – 306 characters = 2 Messages
  • 307 – 459 characters = 3 Messages
  • 460 – 612 characters = 4 Messages
  • 613 – 765 characters = 5 Messages
  • 766 – 918 characters = 6 Messages - (recommended max character length for a joined message)
For Non-GSM (Unicode): 1 Message to 1 x recipient: 1 - 70 characters

For joined segmented Unicode Messages to 1 x recipient:

  • 1 – 67 characters = 1 Message
  • 68 – 134 characters = 2 Messages
  • 135 – 201 characters = 3 Messages
  • 202 – 268 characters = 4 Messages
  • 269 – 335 characters = 5 Messages
  • 336 – 402 characters = 6 Messages - (recommended max character length for a joined messages)
What is a GSM-7 Character and what is a Unicode Character?

The base character set for GSM-7 can be found at the link below:


To go further on why we segment like this, below is a handy excerpt from the above link:

"In a standard GSM text message, all characters are encoded using 7-bit code units, packed together to fill all bits of octets. So, for example, the 140-octet envelope of an SMS,with no other language indicator but only the standard class prefix, can transport up to (140*8)/7=160, that is 160 GSM 7-bit characters (but note that the ESC code counts for one of them, if characters in the high part of the table are used)."

Zoho CRM Integration (New Leads)

Zoho CRM integration works using the Zoho CRM API.

The following will provide instructions on integration of 'New Leads', which uses the Zoho API, as well as call data to create leads.

Further information on the exact API call can be found here:




How it Works

Every 15 minutes we will grab any newly created calls for the project and upload them to the connected Zoho account. Each call will create a new lead with the lead name being a generic name you will input on setup.

Any available call data including recordings will be added to the lead description:

Setup and Settings

To setup the integration, click the Zoho CRM integration from the integration list:

You will now need to connect your Zoho instance by clicking 'Connect your Zoho CRM'.

You will be prompted to authenticate our third party authentication app, once done you will be able to proceed to the settings page, you made need to be an admin with privileges to install apps/use APIs to successfully connect.

You will then be prompted to enter your PropertySID as well as a generic lead name, we recommend using something easily identifiable e.g. 'New Call Lead'.

If you like you can choose to sync only data from a specific IVR key e.g. (1 for sales), this will only work for a single level IVR hosted by use. If you have a multi-layered IVR you will need the integration customised, if the IVR is not hosted with us, this setting will not work and you should specify 'No IVR'.

Once setup, your call data will now sync every 15 minutes, if you would like to sync historical data please get in touch with us.
