Check the SMTP Connection Without Sending
Adds Tools > SMTP Check, which connects and logs in to your configured SMTP server and reports success or the exact error, without sending an email to anyone.
Snippet Library
Email snippets for WordPress
Snippets for the emails WordPress sends: change the sender name and address, add a Reply-To header, send HTML email and turn off notifications you do not need. For site owners who want their messages to arrive and look right.
Email Delivery Check in Site Health
Adds a test to Tools > Site Health that warns when WordPress sends mail with plain PHP mail() instead of SMTP or an API, and when an email has failed recently.
Email Log Under Tools
Keeps a list of the last 100 emails the site tried to send (date, recipient, subject and whether it failed) and shows it under Tools > Email Log.
Full Email Log With Search, Viewer and Resend
Records every outgoing email in its own database table and adds Tools > Mail Log, where you can search, read the full message, resend it, and clear old entries automatically.
Send a Test Email From the Admin
Adds a Tools > Send Test Email screen where administrators can send a test message to any address and see right away whether WordPress could hand it off.
Stop "Data Request Confirmed" Emails to the Admin
Stops WordPress emailing the site admin each time a user confirms a personal data export or erasure request; you can still see requests under Tools.
