Frequently Asked Questions

What does an unknown result mean?

It means Mails did not assign a definitive deliverable or undeliverable result. Review the reason, such as timeout or connection failure, rather than treating it as valid.

How can I revisit a submitted batch?

Keep the batch ID from creation and use it to retrieve the job and results. A missing completion time means the job is still running.

Does a deliverable result guarantee delivery?

It is an address validation result, not evidence that a specific message was sent or delivered.
