How it's measured →12%
of downloads still active
At least 700K of 5.9M lifetime downloads are still running, above its category: the median Email & Marketing plugin keeps 0.9%, across 1,294 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Email & Marketing plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 5 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Your five tags are all earning their place. Each gets you onto page 1 of its own search, so none is worth giving up. “email api”, “mail log” and “oauth” (#4, #4 and #4 untagged) would be the next worth testing if a slot frees up.

Estimated active installs
The public count shows “700K+”. Our estimate pins where the real number sits.
Crossed into this band 30 days ago and a band this size takes about a year or more to cross, so the real count is still just over 700K.
At the current install trend, crossing 800K+ in roughly 117 days.

very helpful plugin…like a lot
Read on wp.org ↗ - ★★★★★ topearner4mo ago
FluentSMTP is a fast, lightweight, and dependable SMTP solution for WordPress. It delivers emails consistently, integrates smoothly with popular mail providers, and avoids the bloat that many other SMTP plugins suffer from. The setup is straightforward, the interface is clean, and the built‑in email logs make troubleshooting effortless. If you’re tired of missing WooCommerce order emails or unreliable WordPress notifications, FluentSMTP is a refreshingly simple and effective fix. It does exactly what an SMTP plugin should do — and it does it well.

I encountered an issue while testing the plugin and sending test emails whereby the sending email button was continuing to spin well after the email was successfully send and received. I received a prompt response to my ticket within an hour and after a few hours of back and forth of trouble shooting it was discovered that the issue was on my side. My GoDaddy server needed to have a couple of extensions turned on, which were disabled by default. After activating in cPanel the PDO and PDO_MYSQL PHP extensions the issue went away quite nicely and the SMTP plugin is now functioning fully. Great support deserving of a 5 star and I am sure the plugin will also perform on a 5-star level when I use it on my live site.

Thank you for providing this free plugin which really is a big help to our little charity. We are able to send emails knowing they will be delivered. It’s easy to set up and there is a useful tester built in to the plugin.

I have used Fluent previously. I have moved a website to Milesweb (Brilliant Hosting!!!) and they support Fluent SMTP using Fluent’s “Other SMTP” as the mailer option, so all my settings were known to me. So very quick to set up, sent a test email and received the confirmation back.Done & Dusted!!!
