WooCommerce relies on WordPress wp_mail() to send order confirmations, shipping notifications, and password resets. To make sure these emails reach customers, route them through mySMTP using the WP Mail SMTP plugin.

​
Prerequisites

  • WooCommerce installed and active on WordPress
  • Admin access to WordPress
  • Your mySMTP credentials (see Setting up SMTP credentials)
  • A verified sending domain

​
SMTP settings

Shared IP plans are only available to customers in Denmark.

​
Connect mySMTP to WordPress

WooCommerce does not have its own SMTP settings. Configure wp_mail() at the WordPress level so all WooCommerce emails use mySMTP.
1

Install and activate WP Mail SMTP

In WordPress, go to Plugins → Add New Plugin. Search for WP Mail SMTP by WPForms, then install and activate it.
2

Configure Other SMTP

Go to WP Mail SMTP → Settings. Under Mailer, choose Other SMTP. Fill in:
  • SMTP Host: your real mySMTP hostname (from your setup email)
  • Encryption: TLS
  • SMTP Port: 587
  • Authentication: On
  • SMTP Username: your mySMTP username
  • SMTP Password: your mySMTP password
3

Set the From email and name

Set From Email to an address on your authenticated domain (for example, orders@yourdomain.com). Set From Name to your store name. Enable Force From Email and Force From Name.
4

Save and test

Click Save Settings, then go to Email Test and send a test email to yourself.

​
Match WooCommerce sender settings to mySMTP

WooCommerce lets you define a sender name and address under WooCommerce → Settings → Emails. These values must match the authenticated domain you use with mySMTP.
1

Open WooCommerce email settings

In WordPress admin, go to WooCommerce → Settings → Emails.
2

Set the From address

Scroll to the bottom of the page. Set From address to the same domain-verified address you configured in WP Mail SMTP (for example, orders@yourdomain.com).
3

Set the From name

Set From name to your store or brand name. This appears in the recipient’s inbox.
4

Save changes

Click Save changes at the bottom of the page.
If the WooCommerce From address uses a different domain than the one authenticated in mySMTP, mailbox providers may reject or filter the mail. Always use the same verified domain.

​
Test order emails

Create a test product and place a test order, or use a sandbox payment gateway. Check that the order confirmation email arrives at the customer address and shows the correct sender name and address. You can also view recent sends and check for errors in the WP Mail SMTP logs, if logging is enabled.

​
Troubleshooting

First confirm the WP Mail SMTP test email succeeds. Then verify that WooCommerce email types are enabled under WooCommerce → Settings → Emails. Make sure the order status changes (for example, from Pending to Processing) because some emails trigger only on status transitions.
Verify SPF, DKIM, and DMARC are configured for your sending domain. See SPF, DKIM, DMARC, and BIMI explained.
Run the Sender Readiness Checklist and Email Header Analyzer in the mySMTP Deliverability Toolbox.
Some WooCommerce email customizer plugins or SMTP plugins conflict with WP Mail SMTP. Disable other email-related plugins temporarily to find the conflict.
