WP Mail SMTP Pro 4.9.0 – Reliable WordPress Email Delivery Plugin

Description

WordPress sends order confirmations, password resets and form notifications using your server’s basic mail function, which spam filters often distrust. WP Mail SMTP Pro swaps that for an authenticated connection to a real email provider, so the messages your site depends on reach the inbox.

The Pro edition adds the visibility you need on a busy site: a full email log with the option to resend, open and click tracking, a backup connection that takes over if the main mailer fails, alerts when sending breaks, and a weekly summary of how your site’s email is doing.

Frequently asked questions

What is WP Mail SMTP Pro?

WP Mail SMTP Pro is a WordPress plugin that sends your site’s emails through an authenticated email service and logs them, improving deliverability.

Why are my WordPress emails going to spam?

Usually because they are sent by the server without proper authentication. Sending through a provider with SPF and DKIM set up fixes most cases.

Can it switch to another mailer if one fails?

Yes. Pro supports a backup connection that is used automatically when the primary mailer fails to send.
