WP Mail SMTP Plugin for Any Email Service Provider
Are your WordPress emails not sending, landing in spam, or failing silently? FluentSMTP is a free WordPress SMTP plugin that fixes email deliverability by routing every wp_mail() call through the email service you choose: Gmail, Google Workspace, Amazon SES, SendGrid, Mailgun, Cloudflare Email, toSend, Postmark, Brevo (Sendinblue), SparkPost, Netcore, Elastic Email, SMTP2GO, Outlook / Office 365, Zoho, or any SMTP host.
FluentSMTP talks to each provider’s own API rather than only SMTP, so your transactional and marketing email goes out quickly and lands in the inbox. Set your From name and email, turn on email logging, add failure alerts, and route different senders to different providers, all from one screen.
Connect as many email services as you want, and FluentSMTP routes each email to the right one based on its From address.
💚 100% Free Forever — No Pro Version, No Upsells, No Paywalls 💚
FluentSMTP is 100% free and open source, and it always will be. There is no “pro” version, no premium add-ons, no locked features, no email capture wall, no nagging upgrade prompts, no feature limits, and no paid tier. Every integration listed here, from Amazon SES, Gmail and Outlook to SendGrid, Mailgun, Cloudflare, toSend, Postmark, Brevo and SparkPost, is fully available at no cost.
The opening of the plugin's own description. The full text, installation notes and changelog are on its WordPress.org page.
Questions the author answers
Why are my WordPress emails not sending or going to spam?
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.
Can I send email via SMTP from my WordPress site using this plugin?
Yes. That is what the plugin is for: it takes over wp_mail() and sends through the SMTP server or email service you connect.
Is FluentSMTP really free?
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.
Can I connect Amazon SES API with FluentSMTP?
Yes. Add your SES access key and secret key, and FluentSMTP sends through the Amazon SES API rather than SMTP.
Can I send WordPress emails with Gmail or Google Workspace?
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.
Can I send WordPress emails with Outlook, Office 365 or Microsoft 365?
Yes. Connect your Microsoft account with OAuth2 and FluentSMTP sends through Microsoft’s Graph API. Single-tenant Entra app registrations are supported.
Latest changelog entry
- Fixed Outlook / Office 365 connections failing to authorize on servers where Microsoft returned an HTML error page instead of a token
- Fixed resending or retrying a logged email dropping every Cc, Bcc and Reply-To address when there were two or more
- Fixed the email log’s To column showing serialized text for emails sent to many recipients. On existing sites, deleting all logs once widens the column
- Fixed plain-text emails losing their line breaks, and anything in angle brackets, in the email log viewer

Where this page's numbers come from
Read from the WordPress.org plugin API on , when WordPress 7.1.4 was the current release. WordPress.org rounds active installs into buckets. These are the directory's figures, not my verdict, and I haven't tested this plugin.
