SMS limits and fallback

The SMS limits and fallback page allows you to configure restrictions on when Autopilot sends SMS messages, observe the maximum SMS message send rates for countries of the numbers configured in your Autopilot account, and define the default/fallback country code, when no country code is specified in a mobile number.

Access the SMS limits and fallback page

To access the SMS limits and fallback page, ensure you have accessed the Setup page, and have clicked through to SMS setup > SMS limits and fallback.

If you change any of these field values (below), click Save towards the end of the page to save all changes you have made to the page.

SMS limits

The SMS limits section allows you to configure restrictions on when Autopilot sends SMS messages, including:

  • the frequency with which customers receive Autopilot-generated SMS messages, and

  • the dates and hours when Autopilot-generated SMS messages triggered from journeys.

These limits are designed to reduce the frequency with which recipients are spammed by Autopilot-generated SMS messages, which in turn aims to reduce their likelihood of unsubscribing from receiving these messages.

Select one of the following checkboxes to activate the required SMS limit restriction:

  • Prevent people receiving more than one SMS every X hours - if you select this checkbox, specify the value for X, and Autopilot will only send SMS messages to each person once every X hours.

  • Do not send SMS within Journeys on specific dates - if you select this checkbox:

    • Click Add a date, then click inside the current date field to use the calendar popup to change the date.

    • To remove a date, click its adjacent bin icon.

    • Click Add another date to add another date to any existing dates.

  • Do not send SMS within Journeys outside of waking hours, except for recipient initiated responses - Autopilot only sends journey-initiated SMS messages during waking hours, or only as responses to recipient-initiated replies.

SMS throughput by country

The SMS throughput by country section presents the maximum SMS message send rates for countries of the numbers configured in your Autopilot account so far.

Currently, Autopilot implements an automatic balancing feature, whereby as you add more numbers to your Autopilot account for a given country, the SMS message send rates are evenly distributed across all configured numbers in your account for that country.

This section only appears when at least one number has been configured in your Autopilot account.

Fallback country code

The Fallback country code section allows you to configure the country code used by Autopilot whenever SMS messages are sent to people whose phone number fields do not include a country prefix.

Set your fallback country code to the country that most people in your customer data platform (CDP) are likely to be located in.
