The report card
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.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | The whole plugin is free, with no Pro edition or paid tier, according to its WordPress.org page. You still pay whatever your mail provider charges. |
| Free plan and trial | A | Free outright with no cap: all features and integrations, no paid edition, and the vendor says it will stay that way. |
| Features | B | Connections to SES, Gmail, Mailgun, SendGrid, Postmark and others, routing, a fallback, an email log with resend, failure alerts and migration from other plugins. Nothing in the listing is held back for a paid tier. |
| Ease of use | C | No store rating on record. You install it in WordPress and connect a provider account. |
| Platforms and integrations | B | Runs inside WordPress and connects to Amazon SES, Gmail, Microsoft 365, Mailgun, SendGrid, Postmark and Brevo. No standalone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
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 it 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
Good to know
Good for
- WordPress site owners who want email logging without paying for a plugin
- Agencies connecting many client sites to their own sending provider
- Sites that want a fallback sending connection
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.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
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.
