Once your message content has been defined, you can use test profiles to preview and test it. If you inserted personalized content, you can check how this content is displayed in the message, using test profile data.

  1. Click Simulate content.

  2. Click Manage test profiles to add a test profile.

  3. Find your test profile with the Identity namespace and Identity value fields. Then, click Add profile.

  4. Once you selected your test profile, you can close the Add test profile window.

  5. From the Preview & test window, test profile data is added to the message content.

Validate your SMS

You must check alerts in the upper section of the editor. Some of them are simple warnings, but others can prevent you from sending the message. Two types of alerts can happen: warnings and errors.

  • Warnings refer to recommendations and best practices. For example, a warning message is displayed if your SMS message is empty.

  • Errors prevent you from testing or activating the journey, or publishing the campaign, as long as they are not resolved. For example, an error message warns you when the subject line is missing.


To improve your deliverability, use the phone numbers in the formats supported by the provider. For example, Twilio and Sinch only support phone numbers in E.164 format.

Send your SMS

When your SMS message is ready, complete the configuration of your journey or campaign to send it.
