Failed Sends and Resending

What a failure actually means, which ones a resend fixes, and how to clear a day where somebody did not get the sheet.

4 min readUpdated August 2026

Two Kinds of Failure

A soft failure is temporary. The mail server was busy, the handset was off the network, the provider deferred and will retry. A hard failure will happen again on every attempt: a landline cannot receive a text, and a mailbox that does not exist will never accept one.

What you seeResend?Real fix
DeferredNo, the provider retriesWait
Soft bounceYesUsually nothing
Hard bounceNoCorrect the email address
Sending failed (SMS)Once, from the SMS tabCheck the number is a mobile
UndeliverableNoGet a working number
No addressNothing was attemptedAdd the address to the record
Important: A landline fails every time. Fix the number in the crew record, then resend.

A Send With a Failure In It
Send the full sheet, then try Resend Failed. The landline fails again, which is the point.

Resending

In the delivery report, the resend button on a row resends the email to that person. Resend to N, above the list, resends to everyone whose email failed. Both resend email only. To retry a failed text, send it again from the SMS tab with just that person ticked. A resend writes a new attempt on the same day, so the report shows both the original failure and what happened the second time.

Interactive Demo
Resending From the Delivery Report
Press Resend. The soft bounce goes through on the second attempt; the mistyped address fails again.

The Blanks Are Not the Same

A channel with nothing in it means either nothing was sent or nothing could be sent. The second is a missing phone number or email in the crew record. Fix it before the next send.

Tip: Missing addresses are listed in a warning at the top of the To and SMS tabs, so you can catch them before you send.

When Nobody Got It

If a whole send fails, check that the production has SMS enabled and that the sending number is provisioned. If the provider is down there is nothing to fix on your end, and the AD Control Center will keep the day marked as not distributed until it actually goes.

A recipient who replied STOP has opted out, and G-Casper Pro will not text them again until they opt back in. Their text shows as Failed in the report, with the reason Recipient has opted out of SMS messages. Resending will not change that. Email still reaches them.

Important: Re-adding somebody who opted out does nothing. Consent is stored against the phone number and only the person holding it can restore it.
