Revolutionary SMTP  ·  version 0.6.8

WordPress email that actually arrives.

Send every message from your site through a real, authenticated connection: Microsoft 365, SendGrid, Postmark, Amazon SES or your own SMTP server. Every email is logged, and when one fails you see the provider's actual error.

  • Microsoft 365 through the Graph API, even where SMTP sign-in is turned off
  • Send as a shared mailbox, with no license and no password
  • An email log, a delivery chart and a test sender built in

Questions

Good to know

Still unsure? Ask us anything.

Microsoft has most likely turned off SMTP sign-in on your tenant. Switch to the Microsoft 365 Graph connection, which does not use SMTP at all.

Yes, with the Graph connection. A shared mailbox needs no license and no password.

No. Admin consent is granted once per app for the whole tenant. Other sites using the same app check again on their own and show Authorized within about 15 minutes.

If it offers SMTP, and nearly all do, use the Custom SMTP connection with the host, port and credentials from your provider.

No. Sending is never blocked. The Revolutionary license, entered once in the Multipurpose Dashboard, turns on automatic updates.

30 days. Older rows are removed automatically, and you can clear the log at any time.

Stop wondering if the email went out.

Revolutionary SMTP is included with every Revolutionary license, together with all sixteen plugins and the Multipurpose theme.
