SMS bounces

An SMS is considered 'bounced' when any of the following happens:

• The phone number doesn't exist
• The phone number is no longer active
• The contact has unsubscribed from receiving SMS
• No delivery report from the recipient's network
• The recipient is unavailable (e.g. no coverage or in flight mode)
• The message expired before it could be delivered
• The phone number is a landline or an IoT device
• The message was blocked by a spam filter for compliance or regulatory reasons.
• The recipient is barred from receiving text messages, e.g. their prepaid needs topping up
• Service outage/Temporary technical problems from the recipient's operator
• Your Sender ID isn't registered in the country you're sending to

Unlike email, Ometria doesn't keep a 'suppression list' for SMS bounces. When our SMS carrier reports that a number is invalid, inactive, or that the contact has opted out, Ometria will automatically unsubscribe that contact from SMS instead. See: Managing text message marketing preferences

Temporary discrepancy in SMS unsubscribes

As Ometria has recently released stop text support, we've only just started collecting data for unsubscribes via text message.

If you had contacts unsubscribing via stop text before this feature was supported, they were unsubscribed by our SMS carrier, but their subscription status wasn't updated in the platform.

We're currently working on syncing these past unsubscribes so that your SMS subscription data is fully up to date. 

Are unsubscribes counted twice?

No.

If you send an SMS to a contact who was already unsubscribed, Ometria counts that as a bounce.

If you send an SMS to a contact who is subscribed but unsubscribes after receiving the campaign (either by clicking the unsubscribe link or sending a STOP text), Ometria counts it as an unsubscribe.
