This plugin when activated automatically redirects all email sent through wp_mail/phpmailer to the user currently logged in or the site administrator.
The redirected email contains information about where the original email would have been sent to.
Use this plugin if you want to test email-sending features without actually sending emails our to anyone but yourself. I wrote this plugin to ease debugging with subscribe2.
Since Version 1.2 you can choose whether to redirect all email to the currently logged in user (default), the site administrator (only wpmu) or the blog administrator.

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.
<h3>🛠 Works with popular SMTP plugins like:</h3>
✅ 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
<h3>🎯 Why use this plugin?</h3>
✔ Ensures MailPoet emails follow your SMTP settings 
✔ Works with Gmail & other SMTP providers MailPoet doesn’t support 
✔ Enables email logging via your SMTP plugin
<h3>⚠ Important notes:</h3>
<ul>
<li>Major MailPoet updates may require adjustments. </li>
<li>Some advanced MailPoet features (like bounce handling) may behave differently. </li>
</ul>
✅ Test your setup with MailPoet test emails and real newsletters to ensure everything runs smoothly!
