Key points

What you see in the admin

Visitors see nothing. The log shows the date, address, subject, sender plugin and result.

What the admin gets

You register an app in your own Microsoft Entra or Google Cloud and sign in once.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, PHP 7.4+.
  • A Microsoft or Google account, or any SMTP server.

Full module description

Mail OAuth & Email Log sends the mail of any WordPress site through Microsoft 365, Gmail or SMTP and shows what happened to each email. WooCommerce shops have a separate version.

What you see in the admin

Visitors see nothing. The log shows the date, address, subject, sender plugin and result.

What the admin gets

You register an app in your own Microsoft Entra or Google Cloud and sign in once. Tokens refresh by themselves, and the screen explains why a connection may have died.

How it works, step by step

  1. You register an app.
  2. You sign in once.
  3. You send a test email.
  4. Site mail goes through this connection.
  5. The log shows the result.

Under the hood

  • Tokens refresh once a day even with no mail.
  • An email shows in a sandboxed frame.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. Open Mail OAuth in the admin, pick a connection and send a test email.
  3. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.
