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)OnceCheck the number is a mobile
UndeliverableNoGet a working number
No addressNothing was attemptedAdd the address to the record
Important: Resending to a landline three times produces three failures and no call sheet. The number in the crew record is the thing to fix.

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

Not sent

Resending

Resend to one person from their row, or resend to everyone who failed in one action. A resend writes a new attempt on the same day, so the report shows both the original failure and what happened the second time.

The Blanks Are Not the Same

A channel with nothing in it means one of two things. Nothing was sent, or nothing could be sent. The second is a missing phone number or email in the crew record, and it is worth fixing before the next send rather than after it.

Tip: Sort by status before a send rather than after. Missing addresses are visible in the recipient list, and finding them at 11pm the night before D1 is worse.

When Nobody Got It

A whole send failing is different from three people failing. 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 is not a delivery failure. They opted out, and G-Casper Pro will not text them again until they opt back in. They show as excluded from the send rather than failed, and 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.
