Reason 1

An earlier email to the vendor's address bounced, so the address is on a suppression list.

When an email bounces, the vendor's address is added to a suppression list, and later emails to it are blocked from being sent until the address is cleared.

1Confirm the send, then clear the suppression list

1. Check the job's Audit Trail to confirm whether the email was actually sent.

2. If the email was sent, contact Technical Support at go.servicetitan.com/ask and ask them to check whether the email bounced and to remove the vendor's address from the suppression list. (Only Support can clear the suppression list.)

3. After Support confirms the address is cleared, go through the steps of sending the purchase order again to confirm the issue is resolved.

✓ Done · The purchase order email sends successfully and the vendor receives it, with no undelivered alert.

If the alert continues, or the Audit Trail shows the email as sent or delivered but the vendor still didn't receive it, contact ServiceTitan Technical Support at go.servicetitan.com/ask with:

• The purchase order number and the vendor's email address

• What the job's Audit Trail shows for the email (sent, delivered, or not sent)

• Whether Support has already cleared the address from the suppression list

• Confirmation that the vendor's email address is spelled correctly

If the email shows as delivered but the vendor still doesn't have it, the vendor's own mail server may be filtering or quarantining it. In that case, the vendor's IT team needs to allow the ServiceTitan sender address.
