Biggest opportunity: Add “comment”, “e mails” and “e mail” to your wp.org tags. You rank #20, #21 and #23 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 3 listed these are the slots worth spending.

1.7%

of downloads still active

At least 10K of 590.8K 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 2 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.
