SMTP Mailer


L’extension SMTP Mailer vous permet de configurer un serveur de messagerie qui gère tous les e-mails sortants de votre site Web. Il prend le contrôle de la fonction wp_mail et utilise SMTP à sa place.

  • Type of Encryption: The encryption to be used when sending an email (TLS/SSL/No Encryption. TLS is recommended).
  • SMTP Port: The port to be used when sending an email (587/465/25). If you choose TLS the port should be set to 587. For SSL use port 465 instead.

Works absolutly fine, nice debug view on testing

Easy WP SMTP seems to be going down hill ever since SendLayer took it over. It just keeps getting more and more bloated. If you want an easy SMTP plugin then this is the one. It does what it says and nothing more.

Great Plugin for extended SMTP Support that has all you need:mail settings, a form for testing the configuration and a proper debug view (something you miss in most other smtp plugins)! No stupid "Pro" Versions that only add bloated and useless stuff like WP Mail SMTP or Easy WP SMTP do. (Honestly, you should manage your mails on your smtp provider, not inside worpdress) And because of its simplicity it works with everything. If you form plugin is not working, the problem lies in the form plugin.

This is THE plugin you need to send e-mails. Forget about WPForms, Easy WP SMTP (after their upgrade it got super-bloated) or others. You just need to send e-mails, and this is the plugin to do it. Easy and lightweight.

After Easy WP SMTP sold the plugin to a company it includes much Bloatware, 9 MB! SMTP Mailer has 52 kb! I switched all projects to SMTP Mailer, took less than a minute. It is small, it does what it should. Not more, not less. Thank you!
