GoDaddy SMTP settings at a glance
| Outgoing (SMTP) host | smtpout.secureserver.net (Workspace Email) — smtp.office365.com (GoDaddy Microsoft 365) — relay-hosting.secureserver.net (unauthenticated relay from GoDaddy hosting only) |
|---|---|
| Ports & encryption |
465 — SSL/TLS <em>(smtpout.secureserver.net)</em>587 — STARTTLS <em>(smtpout.secureserver.net / smtp.office365.com)</em>80 — None <em>(legacy, smtpout only)</em>3535 — None <em>(legacy, smtpout only)</em>25 — None <em>(relay-hosting.secureserver.net from GoDaddy servers)</em> |
| Username | the full mailbox address |
| Password | the mailbox password (Workspace) — Microsoft 365 rules apply for GoDaddy 365 mailboxes |
| Authentication | GoDaddy has migrated most Workspace Email customers to Microsoft 365; if your mailbox is on 365, use smtp.office365.com with SMTP AUTH enabled (see the Office 365 page). |
How to set up GoDaddy SMTP
- Identify the mailbox type in the GoDaddy dashboard (Workspace Email vs Microsoft 365).
- Workspace: host smtpout.secureserver.net, port 465 SSL/TLS (or 587 STARTTLS), username = full address, password = mailbox password.
- Microsoft 365: host smtp.office365.com, port 587, STARTTLS, enable Authenticated SMTP for the mailbox.
- WordPress on GoDaddy hosting without a mailbox: relay-hosting.secureserver.net, port 25, no auth — 250/day only.
Sending limits
- The hosting relay (relay-hosting.secureserver.net) allows 250 relays per day per hosting account and only from GoDaddy servers.
- Workspace mailboxes: about 250 recipients per day; Microsoft 365: 10,000 recipients/day, 30/min.
Things that catch people out
- The 250/day relay limit is the number-one reason GoDaddy-hosted WooCommerce stores stop sending order emails.
Common GoDaddy SMTP errors

When GoDaddy is not enough for your app
When a provider caps you or blocks a port, point the same app at QueenSMTP instead: host smtp.queensmtp.com, port 587 (STARTTLS) or 465 (SSL), your SMTP username and password from the dashboard. $5/year plus $0.10 per 1,000 emails, 100 free a day to test.
