FluentSMTP report card
Very good · out of 4.0 · graded Nov 13, 2026
Best for connecting WordPress to a mail provider for free
FluentSMTP is a free WordPress plugin that sends your site's email through a provider you connect, with a log, a fallback connection and failure alerts. It has no paid version, and you still need an account with a mail provider.
Who FluentSMTP is for
- Fits if you run WordPress and want logs and a fallback without paying
- Works for sites already on Amazon SES or Mailgun that need a way to connect
Who FluentSMTP is not for
- Skip it if you don't run WordPress, as it only works inside it
- Not for you if you want a sending service: it's a connector and deliverability depends on the provider you pick
- Watch out: you need a separate provider account, which has its own pricing
- Watch out: Zoho Mail connects through SMTP, not an API

Keep FluentSMTP, or make your own?
Keep it
FluentSMTP is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 3.2 is higher than 50 of the 50 other email sending services we grade.
What you could make
- Reports: an app builder makes this well.
What you could not
- Mail servers with a good name among inbox providers.
- It plugs into other products, Amazon SES, Gmail and Google Workspace among them.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. FluentSMTP’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is FluentSMTP?
FluentSMTP is a free WordPress plugin that sends the site's email through a provider you connect, such as Amazon SES, Gmail, Mailgun, SendGrid or Postmark, using the provider's API where one exists. It logs emails, reports on delivery, supports a fallback connection and sends failure alerts.
Worth knowing
- Runs only inside WordPress; it needs an account with a separate email provider, which has its own pricing.
- It is a connector, not a sending service, so deliverability depends on the provider you choose.
- Zoho Mail is connected through SMTP rather than an API, according to the plugin listing.
Key features
- Provider connections
- Connects to Amazon SES, Gmail and Google Workspace, Microsoft 365, SendGrid, Mailgun, Postmark, Brevo, SparkPost, SMTP2GO, Elastic Email and any SMTP server.
- Multiple connections and routing
- Several providers can be connected at once, and each email is routed to one based on its From address.
- Fallback connection
- A secondary connection takes over when the primary one fails.
- Email log and resend
- Logs sent emails with headers, body and the server's response, and lets you resend a logged email.
- Failure alerts
- Notifies you by email, Telegram, Slack, Discord or Pushover when delivery fails, according to the plugin listing and the vendor site.
- Migration from other plugins
- Imports settings from WP Mail SMTP or Easy WP SMTP, and works with WP-CLI.
