Biggest opportunity: Swap “transactional email”, “wp mail” and “wp mail smtp” for “wordpress smtp”, “smtp plugin” and “send”. “transactional email” isn't earning its slot: you're not in the first 24 results for its own search. “wordpress smtp” sits at #16 untagged, close enough for a declared tag to move it up. “wp mail” isn't earning its slot: you're not in the first 24 results for its own search. “smtp plugin” sits at #19 untagged, close enough for a declared tag to move it up. “wp mail smtp” isn't earning its slot: it only gets you to #15. “send” sits at #21 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →5.2%
of downloads still active
At least 1K of 19.2K lifetime downloads are still running, above its category: the median Email & Marketing plugin keeps 0.9%, across 1,295 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 1 release 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.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Swap “transactional email”, “wp mail” and “wp mail smtp” for “wordpress smtp”, “smtp plugin” and “send”. “transactional email” isn't earning its slot: you're not in the first 24 results for its own search. “wordpress smtp” sits at #16 untagged, close enough for a declared tag to move it up. “wp mail” isn't earning its slot: you're not in the first 24 results for its own search. “smtp plugin” sits at #19 untagged, close enough for a declared tag to move it up. “wp mail smtp” isn't earning its slot: it only gets you to #15. “send” sits at #21 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “wp mail smtp”. #15 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

All reviews on wp.org ↗- ★★★★★ SrDusky1.2y ago
We host websites on a server that limits the number of files (INODES) we can place in it. I recently replaced an obsolete SendGrid plugin with another, and suddenly I was hitting 85% of my INODE allotment because the new plugin had too many files. I had two options: migrate some of the sites to another server or switch to a lighter plugin. I chose the latter option: “SMTP for SendGrid – YaySMTP” fits my needs perfectly.
