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

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

N/A

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. The recent download trend is too spiky to read.

    The software looks really good. If it worked, it would do exactly what I needed. Like all WP plugins the lack of manual is staggering. I managed to send 60 empty mails to 60 out of 125 intended user. When I later wanted to send a I’m sorry mail. All other software you first select the user, then you write the message. Here you select the send to by sending the message! Thereafter it was not possible to send more mails. Have I hit some unknown limit, that I don’t know about? Trying to build a user list was just as unsuccessful as sending the second mail. Building a user list does not work!

    This plugin really helps to ease the burden of communicating with all subscribers to the page. I really like that it has some sample emails as well, and so the work is not so tedious

    moest wel even leren ermee om te gaan, maar dat gaat heel intuitief. (Toen had ik wel al alle leden 3x een lege mail gestuurd…..) Kijk uit met ‘enter’ 🙂
