Delivery issues and error messages

You can check the delivery status of your messages on the History page in your Textmagic account. Here, you can see whether they’ve been delivered or rejected.

There are various possible reasons for message rejection. Here are the most common ones:

• You’re texting an unregistered number from a Sinch trial account;
• Your Sinch virtual number is not toll-free or 10DLC verified;
• You’re trying to send a message to an unsupported country;
• Your message has been blocked by the carrier’s anti-spam filter;
• Your message contains restricted or prohibited content;
• You don’t have enough balance in your Sinch account;
• You’ve exceeded the messaging rate limit on your Sinch account.

For more information on possible errors, please consult Sinch error code guide.

If this is the case, Textmagic will display Rejected or Failed in the Status column and inform you that Sinch has blocked your message. This error message will also direct you to check the provider’s log details on the Message search page to find out the reason for rejection and troubleshoot it.
