Biggest opportunity: One page off on “mailster”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
Not scored yet. Nobody has reviewed this plugin, so a grade would come from directory averages rather than from anything measured here.

How it's measured →1.0%
of downloads still active
At least 100 of 10.4K lifetime downloads are still running, in line with 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.

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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| deliverymethod | #1 | #2 | 0 |
| mailsteresp your tag | #3 | #3 | 0 |
| sparkpost your tag | #5 | #18 | down 1 |
| mailster your tag | #14 | #21 | up 8 |
| email your tag | Not in the top 24 | ||
| newsletter your tag | Not in the top 24 | ||
7 searches this plugin appeared in over the last 90 days, 4 listed. 3 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.
What to do about it
- One page off on “mailster”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
- “email” and “newsletter” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.
- Already on top for “deliverymethod”. #1 without listing it. A tag would change little there; your slots are better spent on a search you don't yet win.

Directory rank
Ranked about #13,300 to #16,400, alongside the other plugins at 100+ installs. Plugins with the same install count swap places between wp.org requests, so this is where most of them sit. Checked monthly, last on 21 Oct 2026.
Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.
