How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

At the current install trend, crossing 200+ in roughly 1001 days.

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.

   This plugin is really simple but very useful to solve all the problems related to php mail() function. I use it with Amazon SES but they work with any SMTP server. It has fixed issues on many of my websites. And what’s more, it’s free, unlike the others!
