Frequently Asked Questions

Common questions about FluentSMTP – WP Mail SMTP Plugin with Amazon SES, SendGrid, Mailgun, Postmark, Cloudflare, toSend, Gmail and Any SMTP

By default WordPress sends email with the PHP mail() function on your web server, which is often unauthenticated, rate limited, or blocked outright by the host. Mailbox providers then reject or junk it. FluentSMTP sends your email through a proper email service or SMTP server instead, authenticated with your own domain, so it is delivered and lands in the inbox.

Yes. That is what the plugin is for: it takes over wp_mail() and sends through the SMTP server or email service you connect.

Yes. There is no pro version, no paid add-on and no feature limit. Every provider and every feature is in the free plugin, and it will stay that way.

Yes. Add your SES access key and secret key, and FluentSMTP sends through the Amazon SES API rather than SMTP.

Yes. Connect your Google account with OAuth and FluentSMTP sends through the Gmail API. You can also use Gmail's SMTP server with an app password if you prefer.

Yes. Connect your Microsoft account with OAuth2 and FluentSMTP sends through Microsoft's Graph API. Single-tenant Entra app registrations are supported.

Yes. When you create a connection you choose where its credentials are kept: in the database, or in your wp-config.php file, which is what we recommend.

Yes. FluentSMTP connects to SendGrid over their API, which is faster than their SMTP endpoint. If you would rather use SMTP, you can set that up instead.

Yes. FluentSMTP connects to Mailgun with an API key, which is faster than their SMTP endpoint. If you would rather use SMTP, you can set that up instead.

Yes. FluentSMTP connects to Brevo (formerly Sendinblue) with an API key. If you would rather use SMTP, you can set that up instead.
