Send test SMS messages

Article: 000054622
Updated: September 16, 2025

Test your SMS messages by delivering them to a registered phone number for a 1-to-1 look at what your contacts will see.

While our SMS preview feature gives you a quick look at how your messages will appear, you’ll only be able to see your variables and get a general idea of how your longer messages will be split. With a test send, you’ll see exactly what your contacts will experience before launching full campaigns.

Set up your account for tests

To complete a test send, you must have purchased the SMS marketing add-on and have completed the registration process. To send your first test, you’ll need to add a phone number and opt that number in to receive SMS messages.

Once a number has been added for SMS test sends, an ‘SMS Test Sends’ list will be auto-generated, containing your testing phone number(s). These numbers will be contacts in your Constant Contact account—contacts that have opted in for SMS—but they will not be included in your standard lists alongside all of your other contacts. Instead, they will be contained in this auto-generated list.
