    A dashboard that answers one question

    Is mail being delivered right now? The dashboard shows the last delivery, what is waiting in the retry queue, and what could not be delivered — at a glance.

    Pick a mail service, send a test

    Google, SendGrid, Resend, Brevo, Postmark, Mailgun, SMTP2GO or any SMTP server — and with Pro, Microsoft 365, Amazon SES and Zoho. Choose one and every message goes out over it.

  • Step 1 of 5 of the setup wizard, asking how the site should send its email.

    03

    Guided setup in five steps

    Choose a service, enter credentials, verify them against the provider and send one real message — in that order, so you know it works before you rely on it.

  • The Settings screen with reliability, failure detection, privacy and setup wizard sections.

    04

    Failure detection you control

    Decide how many failures in a row count as an outage and how long the retry queue holds a message. When sending breaks, an admin notice appears and Site Health turns red.

Pro Features

Features that keep every email moving.

Pro builds on the free plugin with more mail services, deeper visibility and automatic failover.

  • Microsoft 365 & Outlook

    Send through Microsoft 365 and Outlook mailboxes, alongside every connection in the free plugin.

  • Amazon SES & Zoho

    Two more high-volume mail services, ready to connect with their own credentials.

  • One-Click Google Sign-In

    Connect a Gmail or Google Workspace mailbox without setting up your own OAuth client.

  • Email Logs

    An optional record of what your site sent, for the sites that need an audit trail.

  • Open & Click Tracking

    See whether important messages were opened and their links clicked.

  • Backup Connection

    When the primary service fails, mail goes out over a second connection instead.

  • Smart Routing

    Send different kinds of mail through different connections.

  • Failure Alerts

    Get told the moment sending starts failing — not when a customer complains.

  • Rate Limiting

    Stay inside your provider's sending limits automatically.

FAQ

Questions & Answers

Something else? Ask the developers .

Do I need the free plugin too?

Yes. Pro is an add-on — it extends MME-Mail to SMTP rather than replacing it. Install the free plugin, then install and activate Pro and enter your license.

Does it work with WooCommerce and form plugins?

Yes. Everything that sends through wp_mail() — WooCommerce, Contact Form 7, Gravity Forms, WPForms and almost every other plugin — goes out over your connection.

Can another mailer plugin be active at the same time?

No. WordPress lets exactly one plugin take over sending. The plugin detects the common ones and tells you on screen.

Does my license expire?

No. Every plan is a one-time purchase with lifetime updates. Basic covers 1 domain, Professional 5 and Ultimate unlimited; moving a site to a new domain frees the old one automatically.

How large can attachments be?

On the Google API path, about 2 MB. Oversized messages are rejected before sending with a clear message, rather than failing on the wire.
