Post SMTP – Logging and failure alerts

Post SMTP is a delivery-focused SMTP plugin with detailed logging, failure notifications, and a connectivity wizard.

Easy WP SMTP – Simple setup

Easy WP SMTP is a lightweight, straightforward SMTP plugin focused on getting mail working with minimal fuss. Against WP Mail SMTP, it is simpler and quicker for a basic configuration. What it does not do: it has fewer provider integrations and less logging depth than the fuller plugins here.

SMTP Mailer – Minimal and free

SMTP Mailer is a minimal plugin that does one job, route WordPress mail through an SMTP server, without extra features. Against WP Mail SMTP, it is smaller and completely free. What it does not do: it offers no logging or provider-specific wizards, so troubleshooting is more manual.

Choose SMTP Mailer if you want a minimal, no-frills mailer.

When to stay on WP Mail SMTP

Stay on WP Mail SMTP if you are already using it successfully and value its guided setup wizard and large documentation library, which make it the most beginner-friendly option. If you do not need email logging, the free version does its core job well. Reconfiguring mail is low-effort, but there is no reason to switch a working setup without one.
