How to Godaddy smtp relay
Published October 12, 2024 · Updated July 22, 2026 · Guides & Tutorials
Your GoDaddy SMTP relay was working, and now your emails have gone quiet — or they never worked at all. GoDaddy's relay is convenient but easy to trip up, and a handful of issues cause almost every failure. Here is how to troubleshoot a GoDaddy SMTP relay and get your mail flowing again.
The usual suspects
- Daily limit reached. GoDaddy caps the relay at a few hundred emails a day — hit it and sending silently stops until the next day.
- Wrong host or port. Hosted sites use
relay-hosting.secureserver.net; mailboxes usesmtpout.secureserver.net. Mixing them up breaks sending. - Wrong "from" address. The relay expects a sender on your GoDaddy-hosted domain.
- Missing authentication. Even relayed mail needs SPF/DKIM/DMARC to reach external inboxes.
How to fix it, step by step
- Check whether you have hit the daily cap — if so, that is your answer.
- Verify the host and port match your setup (hosted relay vs mailbox).
- Confirm the "from" address is on your domain.
- Test with a single message and read the error, not just "failed."
- If deliverability is the issue, confirm SPF, DKIM, and DMARC pass.

Frequently asked questions
Why did my GoDaddy SMTP relay stop working?
Most often you hit the daily cap, or a host/port/from-address mismatch. Check the limit first, then verify your settings.
How many emails can GoDaddy's relay send?
Only a few hundred per day on shared hosting — enough for contact forms, not campaigns.
What's the reliable alternative?
A dedicated SMTP with a dedicated IP and no cap — it removes the limits and the troubleshooting for good.
