How it's measured →1.1%
of downloads still active
At least 20 of 1.8K lifetime downloads are still running, in line with its category: the median Email & Marketing plugin keeps 1.0%, across 1,186 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.

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.
| Keyword | wp.org | On merit | Change |
|---|---|---|---|
| phpmail | #5 | #7 | — |
| relay | #5 | #10 | 0 |
| aws smtp | #13 | #18 | 0 |
| change mail sender | #14 | #21 | +2 |
| mail logging | #21 | #21 | — |
What to do about it
- Add “phpmail”, “relay” and “aws smtp” to your wp.org tags. You already rank #5, #5 and #13 for them without listing them. WordPress.org counts only your first five tags, so these are the slots worth spending.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.
