# Email Not Receiving: Troubleshooting Guide

Incoming mail problems may involve DNS, mailbox quota, filters or sender-side rejection.

## Check in Order

1. Send a test from an external provider.
2. Confirm the domain and MX records are active.
3. Check mailbox quota.
4. Review Junk, filters and forwarding rules.
5. Check whether the message bounced back to the sender.
6. Confirm the mailbox exists and spelling is correct.
7. Review mail logs through support when necessary.

## Useful Evidence

Ask the sender for the complete bounce message, sending time and recipient address.

## Need Help?

If you still need assistance, open a support ticket through your Vertico client account and include the affected domain or email address, a screenshot of the error, and the approximate time the problem occurred. Never send passwords by email or support ticket.
