Subscribe2 – Form, Email Subscribers & Newsletters

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

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.

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 declining trend compresses what a buyer would pay.

   I’m trying to bulk subscribe WordPress users to all categories created from registered subscribers. I select “All” and then “All Categories” and click the “Bulk Update Categories” button, but it’s not working. How can I fix this? Thank you very much. Intento suscribir masivamente a usuarios de wordpress a todas las categorías creadas desde suscriptores registrados, selecciono todos y al final todas las categorías y haco clic en el botón bulk update categorias, pero no funciona. Como puedo solucionarlo. Muchas gracias.

   For years I used this with no problem. Then suddenly I started getting daily “mail suspended temporarily because daily limit exceeded” notices from my web host. I deactivated Subscribe2 and the problem stopped. Draw your own conclusions.

   I’ve been using this for a while but it needs a big fix. The plugin should send mail singly and spread out over time rather than all at once. I’m getting complaints from my ISP that the plugin is overloading the server with huge dumps of email. I only have about 1,500 subscribers and if that is overloading then I can only imagine how bad it must be with more popular blogs. Please implement this. I just downgraded my review from five stars to one star. See… there’s a problem that this plugin creates: it overloads the servers with email as described above. I just discovered that the developer is offering a fix for that for $29.99 PER FREAKING YEAR!!!!! It was bad enough that the developer creates a problem and then offers to solve it for a fee. It was worse that the fee is kind of high – I finally decided to pay it untill I discovered… It is absurd that the fee is a reoccurring annual subscription. No thanks.
