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.
Estimated active installs
The public count shows “300+”. Our estimate pins where the real number sits.

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
We can't see a pro tier, so this plugin may earn little or nothing from these installs. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.
How we estimate this
Assumptions
- Free → paid conversion. 0.05%–0.5% of active installs pay for something. No pro tier is visible, so this band starts near zero.
- Annual price per customer. $49–$149 a year, typical for Email & Marketing plugins rather than this plugin's own pricing.
- Acquisition multiple. 1.5x–2.5x annual revenue, the going range for small WordPress-plugin businesses, compressed because the install trend is declining.
- Install base. 300–400 active installs, from our install estimate (wp.org only publishes the floor).

Revenue is installs × conversion × price; value is revenue × a typical acquisition multiple. Every factor is an assumption band, so the output is a wide range on purpose. If you're buying or selling, treat this as a starting point for due diligence.
