Sender name

Enter a Sender name for your SMS. We recommend the sender name to be no less than 3 characters and no longer than 11. Some devices will not display sender names shorter than 3 characters correctly.

The accepted sender name characters are the following: A-Z, a-z, 0-9. The sender name may not be only numbers.


SMS Message

Write your SMS text in the message field.

Content

Your character limit per SMS is 160 characters. Consider this as an opportunity to be short and sweet. Longer messages will be sent as multiple SMS, and the use of special characters will affect the maximum character count per SMS. Read more under Characters.

The number of character used in indicated in the top right corner of the message.

Remember to add an unsubscribe link, to provide the possibility to opt out! Add Unsubscribe link by using the Unsubscribe Data tag.

Links

Extend the journey with a link to your SMS. You may add links as www.heartland.com, http://heartland.com or https://heartland.com. The link will be turned into a short aps.is/ link upon sending.

Ensure that your visitor's browsing data is correctly tracked and saved as an Event in their Profile, by only using full links. Profile merge will not take place if the visitor clicks on a shortened link, or any link that will redirect the visitor and not include GET query parameters.


Data tags

Use Data tags to add a person's details. The tag will be replaced with the data that corresponds to the tag (the Attribute). Example: A tag like ##firstname## should look like a recipients name when received (for example Maria). Read more about Data tags and how to use them here.

Inserting Data tag

To insert a data tag, type ## and choose a data tag from the dropdown menu. We support both default and Custom attributes.

Remember to include the Unsubscribe data tag! ##Unsubscribe## to all SMS messages.

Data tags length = 7 characters

Regardless of actual length, all data tags will count as 7 characters in the SMS Content step. When your message is ready to be sent, the real character count will be calculated per SMS and the credit price of your SMS sending will change accordingly.

The reason for this is that the character count for each SMS will inevitably differ, depending on the members of your Audience and their corresponding data.


Characters

Standard SMS Characters

The characters considered as "special characters" are those not included in the GSM Character Set (GSM 03.38), which are contained in the following table:

SMS with more than 160 Characters

A single SMS includes 160 characters. If your SMS exceeds this number, it will be sent as two, or more, linked SMS. The number of characters per linked SMS also depends on whether it contains special characters.

Special characters require extra encoding and will shorten your message's character limit to 70 characters.

Here's a table to help you visualise how the SMS content affects the character count:

Emojis

Emojis are supported by APSIS One and are regarded as special characters. Emojis consists of 2 to 7 Unicode characters.

A regular smiley😀consists of 2 Unicode characters, while more advanced emojis with defined gender, profession and skin-color requires more. For example, woman office worker: medium skin tone👩🏽‍💼, consists of 4 Unicode characters.

All emojis are not supported in all SMS clients, and might look different depending on the client rendering.
