Not scored yet. Nobody has reviewed this plugin, so a grade would come from directory averages rather than from anything measured here.
Install conversion
How it's measured →6.2%
of downloads still active
At least 400 of 6.4K lifetime downloads are still running, above its category: the median Forms plugin keeps 1.2%, across 1,668 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Forms 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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| mailster your tag | #12 | #19 | down 6 |

What to do about it
- Slipping on “mailster”. Down 6 places since 2026-10-15, now #12. Check what shipped around then, and what moved above you.
- “captcha”, “forms” 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.
