What to Do When You Can't Send or Receive Email

Published on Jun 29, 2026 Updated on Sep 14, 2026 103 views

Email problems are stressful because they're often invisible until someone tells you a message never arrived. Work through these checks in order.

Check Your Mailbox Storage

A full mailbox silently rejects incoming mail in many configurations. This is the single most common cause and the easiest to fix.

Verify Your DNS Records

A recently changed or incorrect MX record will misdirect or completely block incoming mail. Confirm your MX records still point to the correct mail server.

Check for a Blocked or Blacklisted IP

If outgoing mail isn't reaching recipients, your sending server's IP may have landed on a spam blacklist. Free blacklist-checking tools can confirm this quickly.

Confirm Your Client Settings Are Current

A recently changed password or server setting that wasn't updated in your mail client (Outlook, phone, etc.) is a common and simple cause of send/receive failures.

Look for a Specific Error Message

Bounce-back messages usually include a specific error code or reason, which narrows down the cause far faster than guessing.

Still Stuck?

Open a support ticket with the specific error message and roughly when the problem started — that detail lets our team diagnose the issue much faster than "email isn't working."
