Smooth SMTP for WordPress

Smooth SMTP gives you full control over how WordPress sends email. Configure SMTP as your primary sending method, set up a fallback for when things go wrong, get notified through your preferred channels, and keep a detailed log of every email your site sends.

Primary Sending Method (SMTP)

Configure any SMTP provider as your primary sending method. If you leave SMTP disabled, WordPress will continue using its default PHP mail — either way, all other features still work.

Works with any SMTP provider: Gmail, SendGrid, Amazon SES, Mailgun, and more

Configurable host, port, encryption (SSL/TLS), username, password, from email, and from name

Secure credential storage using WordPress’s built-in options API

Fallback Sending Method

If the primary sending method fails, Smooth SMTP can automatically retry using a fallback. This works regardless of whether you’re using SMTP or WordPress’s default PHP mail as your primary.

Fallback to WordPress Default (PHP mail) or a second SMTP server
