Biggest opportunity: Add “sendmail” to your wp.org tags. You rank #24 for it without listing it, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 1 listed it's a slot worth spending.

Install conversion
How it's measured →0.3%
of downloads still active
At least 100 of 38.2K lifetime downloads are still running, below 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.
High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.0.0, well behind 6.8.

Get the full rank-higher report →Search visibility
How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
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 |
|---|---|---|---|
| sendmail | #24 | #23 | down 2 |
| email your tag | Not in the top 24 | ||
1 search this plugin appeared in over the last 90 days. 1 of its tags isn't in the top 24 for their own search.
What to do about it
- Add “sendmail” to your wp.org tags. You rank #24 for it without listing it, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 1 listed it's a slot worth spending.

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.

Many thanks to Will and Tony for this plugin. I have wp-sendgrid successfully installed on a WordPress Multisite instance. The official SendGrid plugin doesn’t appear to support Multisite network activation at this stage (2016/07/22).
