Beschrijving

By default, MailPoet sends emails via PHP Mail, its premium MailPoet Sending Service, or services like Amazon SES or SendGrid. But there’s a catch: Some SMTP providers (like Gmail) aren’t supported, and email logging isn’t possible.

➡ This plugin fixes that. It ensures all MailPoet newsletters are sent via your chosen SMTP plugin, so your WordPress email settings apply to newsletters, too – without extra setup or extra costs.

🛠 Werkt met populaire SMTP plugins zoals:

✅ WP Mail SMTP (by WPForms – the most widely used SMTP plugin)
✅ FluentSMTP (lightweight, free, GDPR-friendly)
✅ Post SMTP (supports OAuth for Gmail, Outlook, etc.)
✅ Easy WP SMTP (simple & reliable)
✅ MailerSend, Brevo (formerly Sendinblue), and more

🎯 Waarom deze plugin gebruiken?

✔ Ensures MailPoet emails follow your SMTP settings
✔ Works with Gmail & other SMTP providers MailPoet doesn’t support
✔ Enables email logging via your SMTP plugin

⚠ Belangrijke opmerkingen:

Grote MailPoet updates kunnen aanpassingen vereisen.
Sommige geavanceerde MailPoet functies (zoals bounce afhandeling) kunnen zich anders gedragen.

✅ Test your setup with MailPoet test emails and real newsletters to ensure everything runs smoothly!

Installatie

Download or clone this plugin into your /wp-content/plugins/ directory.
Zorg ervoor dat de map een naam krijgt als omppm-override-phpmail-mailpoet.
Go to Plugins in your WordPress admin area and activate Override PHP Mail for Mailpoet (via wp_mail).
In MailPoet > Settings, choose “Server (Standard)” or “PHP mail” as your sending method (so it normally uses PHPMail).
Configure your SMTP method in WP Mail SMTP (or your preferred SMTP plugin).
- If you’re using Gmail API or another specialized flow, ensure it’s properly set up in WP Mail SMTP.
Verstuur een testnieuwsbrief (of gebruik de MailPoet testmail) en controleer via WP Mail SMTP logs of e-mail headers dat de mail via je gewenste SMTP provider gaat.

FAQ

Does this plugin replace MailPoet’s default sending method completely?

Ja. Voor alle nieuwsbrieven en testmails die normaal gesproken “PHPMail” zouden gebruiken, wordt het omgeleid naar wp_mail(). Als je echter MailPoets eigen “MailPoet verzenddienst” of “SendGrid” gebruikt, blijven deze onaangetast.

Werkt deze plugin met MailPoet 4, 5, of toekomstige versies?

It has been tested with MailPoet 5.x. MailPoet may change internal classes or architecture in future updates, which could break this override approach. We recommend testing on a staging site whenever you update MailPoet.

Wat als mijn e-mails nog steeds via `mail()` lijken te gaan?

Double-check that you have the correct sending method set in MailPoet (“Server” / “PHP mail”), not an external SMTP inside MailPoet’s own configuration.
Controleer of WP Mail SMTP (of een andere SMTP plugin) actief en geconfigureerd is.
Check if the MailPoet test emails differ from real newsletter sends. Sometimes the test mail can take a different route.

Vereist deze plugin codewijzigingen in MailPoet?

No. But internally, it uses a “class alias” hack to replace MailPoet’s PHPMail class on the fly, which can be update-sensitive. If you see errors or your newsletter fails after a MailPoet update, deactivate and re-check plugin compatibility.

SMTP Mail Control for MailPoet is a fantastic plugin! It's easy to set up (no configuration necessary) and works flawlessly. The integration with MailPoet is seamless. It's highly recommended for anyone who wants to use MailPoet with an existing self-selected SMTP plugin (in my case WP Mail SMTP with Google Workspace OAuth). Keep up the great work! 👍 Vielen Dank, Saskia. 🙏

I like MailPoet but I really wanted to use FluentSMTP as it comes with mail logging and push notifications through Telegram in case mails can't be send which is great. And it comes with a fallback connection. Surprisingly, MailPoet didn't support most of that stuff and therefore I'm really happy and grateful to have found this plugin. Sometimes things get logged twice in FluentSMTP but that's no problem. Big thanks to the developer and please keep up your great work.

I must admit, I was surprised to learn that I wasn't able to log my SMTP traffic using vanilla Mailpoet out of the box. I've been using several SMTP plugins over the years, and they are in reality mandatory if you want to ensure predictable delivery of emails sent from the web server, including SSL encryption and authentication. Not to forget logging, which is crucial to debug any delivery issues. I've tested Override PHP Mail for Mailpoet with FluentSMTP and so far it works perfectly. All outgoing mail is now being logged and can be monitored within the dashboard. To make sure I have a fallback available, I did the following: first I set up the standard Mailpoet SMTP sending method, including its settings for SMTP host name, port, username, password and SSL, and made sure that worked. then I configured FluentSMTP with the same SMTP settings, and made sure that worked too. finally, I switched Mailpoet send with from SMTP to Your web host / web server (php), and performed a final test, including checking the newsletter was logged in FluentSMTP. It was. That way, should the override fail, I should be able to disable the plugin and toggle Mailpoet back to SMTP and carry on as usual, albeit without the logging. Nice work, and thank you so much for sharing ⭐⭐⭐⭐⭐

1.2.6

Release date: September 12th 2026
– Update the donation links to the current Isla Studio donation page.

1.2.5

Release date: September 12th 2026
– Fix MailPoet error formatting after a failed send and reliably restore the recursion guard.
– Continue the newsletter queue after verified permanent SMTP recipient rejections; retain retries for temporary, authentication, connection and policy failures.
– Replace message-content debug logs with at most 100 private diagnostic events; clearing them preserves the shared WordPress log.

– Require the complete PHP, Playground, Plugin Check and native queue E2E checks before release.

Minimum PHP requirement corrected to 8.1: the enum-based email type support introduced in 1.2.0 is PHP 8.1+ syntax, so PHP 8.0 sites could never load versions 1.2.0-1.2.4 (parse error at load time)
Removed the resulting dead PHP 8.0 fallback code paths
The GPL license file now ships with the plugin
