Biggest opportunity: Swap “email” for “smart routing”. “email” isn't earning its slot: you're not in the first 24 results for its own search. “smart routing” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →0.8%
of downloads still active
At least 20 of 2.6K lifetime downloads are still running, in line with its category: the median Email & Marketing plugin keeps 1.0%, across 1,287 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.
