Email Trace (also called Track Delivery) helps you diagnose delivery problems by showing whether a message was accepted, deferred, or rejected by the mail server.
Trace a message
- Go to Email → Track Delivery or Email → Email Deliverability.
- Enter the recipient email address and optionally the sender address or date range.
- Click Run Report or Show.
- Review the delivery log for the message status and any error details.
Understanding results
- Delivered — the server accepted the message for delivery to the recipient mailbox.
- Deferred — temporary failure; the server will retry delivery.
- Failed/Rejected — the message was not delivered; check the reason code for details.
If mail to external providers is failing, also verify SPF, DKIM, and DMARC records under Email → Email Deliverability.
