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

WordPress Mail SMTP Plugin For Any Email Service Provider

Are your WordPress emails not sending, landing in spam, or failing silently? FluentSMTP is the ultimate WP Mail SMTP plugin that fixes email deliverability by routing wp_mail() through your chosen email service — Gmail, Amazon SES, SendGrid, Mailgun, Cloudflare Email, toSend, Postmark, Brevo (Sendinblue), SparkPost, Outlook / Office 365, Zoho, or any SMTP host.

FluentSMTP connects natively to each provider’s API (not just SMTP), so your transactional and marketing emails ship fast, secure, and reach the inbox. Reconfigure your sender, enable logging, add real-time failure alerts, and route different senders to different providers — all from a single clean UI.

Connect as many email service providers as you want, and FluentSMTP will route your transactional and marketing emails automatically based on the From Address. This is one of the unique features that FluentSMTP has to offer.

💚 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.
