First off, WPSubscription is an excellent WordPress plugin! I have been a WordPress designer for years now and have rarely come across a plugin I like this much. With WPSubscription on AppSumo, you get a membership management plugin that is loaded and ready to go with premium features for a one-time fee. Tier 3 checking in -- but no matter which tier you choose, the cost-saving benefits alone are enough to make this a worth-while investment if you plan on offering a subscription-based service on your WordPress site. However, the biggest reason this plugin is so valuable (at least at the time of writing this review) is just how friendly and responsive their customer service team is to ideas and feature requests. They are constantly making sure the plugin stays up-to-date with the most current version of WordPress, they send information e-mails concerning recent feature updates, and best of all they actually listen and respond. They really see to be trying their best to make WPSubscription the best, all-in-one subscription plugin for WordPress. They are serious about wanting to hear from users and seem to do their best to implement feature ideas. Each time I have sent in a feature idea, I have received a friendly, favorable response. In fact, once a couple of months ago, one of the more well-know subscription plugins I had been using on one of my sites had a critical error and actually took down the site for a moment (a learning experience for me). Luckily, this was caught and fixed quickly. That plugin was removed and I placed WPSubscription in its place with no issues whatsoever and the site has been up and running ever since (of course other measures have been taken as well to, helpfully not have that happen again, but so far have not been needed because of how consistent and meticulous they are about keeping WPSubscription up-to-date). I am excited to see how this company grows and look forward to the journey. Thank you WPSubscription and AppSumo for an excellent product.
