Meow Mailer – Free SMTP, Everything Included for WordPress

Never miss a failure. A dashboard warning appears when emails fail, so silent problems don’t go unnoticed. Dismiss it once you have had a look and it stays away until a new email fails.

Failure alerts by email, free. Get told when your site stops being able to send, instead of finding out from a customer. The alert is sent by WordPress itself rather than your provider, so it still reaches you when the provider is the thing that broke. One alert per hour at most, however many emails fail.

Alerts on Slack, Discord or Teams, free. Paste a webhook URL and the alerts and the weekly summary are posted to your chat as well, so finding out that email is broken never depends on email. Handy when you look after a lot of sites. Individual emails are never posted anywhere: this tells you about your site, not about the people it writes to.

Weekly summary, free. A short email with what was sent, what failed, and the most common errors. Nothing is sent on a quiet week.

Control WordPress’s own emails. Switch off the notifications WordPress sends by itself: new user registrations, password and email change confirmations, comment moderation, automatic update reports. Password resets are never affected, so nobody gets locked out.

Background sending. Email goes out after the page has loaded, so your visitors never wait on the mail server.

Offline mode. Capture every email in the log without sending. Perfect for staging and development.

Filters and export. Filter by status and provider, search by subject or recipient, and export to CSV.

Test and resend. Check your setup with an HTML or plain text test, and resend any logged message in one click.

Auto prune. Keep logs forever, or delete anything older than 7, 30 or 90 days.

Multisite ready. Set your provider up once on the main site and let every site of the network use it, or leave each site to configure its own. Email logs always stay per site.

Light and private. No bloat, no tracking. Your credentials can live in wp-config.php instead of the database.

What Meow Mailer will never do No open or click tracking. Other email plugins advertise it as a premium feature. It works by putting an invisible pixel in every message and rewriting every link to pass through a redirect, which means logging when your recipients read their mail and what they clicked. That is surveillance of the people your site writes to, it is personal data you then have to account for under the GDPR, and rewritten links make your email look more like spam, not less. Meow Mailer does not do it, and that is not a gap waiting to be filled in a Pro version. There is no Pro version.

Supported providers Generic SMTP, Mailgun, Brevo, SendGrid, Amazon SES, Postmark, SMTP2GO, Mailjet, Resend, MailerSend, Maileroo, Gmail / Google Workspace (OAuth 2.0), Microsoft 365 / Outlook (OAuth 2.0), and Zoho Mail (OAuth 2.0).

About Meow Apps Meow Mailer is part of the Meow Apps family of plugins, focused on doing one thing well with a clean, modern interface.

External services Meow Mailer contacts an external service only after you choose and configure an email provider. Until then (the default “None”) and in “Offline” mode, it sends nothing anywhere.

When you pick a provider, your outgoing email (recipients, subject, body, headers and attachments) and the credentials you entered are sent to that provider so it can be delivered, and only when your site actually sends an email. For Gmail, Microsoft 365 and Zoho Mail, Meow Mailer also contacts their OAuth servers when you connect and refresh your account. Nothing else is ever sent.

You choose a single provider. Generic SMTP talks only to the server you configure. For the others, please review their terms and privacy policy: Mailgun (terms, privacy), Brevo (terms, privacy), SendGrid (terms, privacy), Amazon SES (terms, privacy), Postmark (terms, privacy), SMTP2GO (terms, privacy), Mailjet (terms, privacy), Resend (terms, privacy), MailerSend (terms and privacy), Maileroo (terms, privacy), Gmail (terms, privacy), Microsoft 365 (terms, privacy), and Zoho Mail (terms, privacy).

Development Meow Mailer is open source. The full source, including the React code used to build the admin interface, lives on GitHub.
