How to Godaddy smtp relay server

Published November 1, 2024 · Updated July 18, 2026 · SMTP & Deliverability

If your website is hosted on GoDaddy, its built-in SMTP relay is the quickest way to get your contact forms and app notifications sending. It is convenient and already there — but it comes with a famously low daily cap that catches a lot of site owners by surprise. Here is how the GoDaddy SMTP relay server works and where you outgrow it.

What the GoDaddy SMTP relay is

GoDaddy provides a relay host (commonly relay-hosting.secureserver.net) for mail sent from websites hosted on its servers. It requires no authentication when you send from within GoDaddy hosting, which makes it easy for scripts and contact forms. The trade-off is a tight limit: shared hosting plans typically allow only around 250–500 relayed emails per day.

How to use the GoDaddy relay

  1. In your app or form mailer, set the SMTP host to GoDaddy's relay host.
  2. Use port 25 (or as specified for your plan), with no authentication when sending from GoDaddy hosting.
  3. Set your "from" address to a mailbox on your GoDaddy-hosted domain.
  4. Keep volume under the daily cap — it is meant for transactional trickles, not campaigns.
The wall you'll hit: That ~250/day cap is fine for a contact form, but it stops a newsletter dead. And because it is a shared relay, you have little control over deliverability once volume rises.
