Biggest opportunity: Swap “amazon”, “newsletter” and “ses” for “bounce”, “amazon ses” and “aws”. “amazon” isn't earning its slot: you're not in the first 24 results for its own search. “bounce” sits at #9 untagged, close enough for a declared tag to move it up. “newsletter” isn't earning its slot: you're not in the first 24 results for its own search. “amazon ses” sits at #10 untagged, close enough for a declared tag to move it up. “ses” isn't earning its slot: it only gets you to #14. “aws” sits at #10 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

1.6%

of downloads still active

At least 1K of 63K lifetime downloads are still running, above its category: the median Email & Marketing plugin keeps 0.9%, across 1,294 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.
