I really liked the look and ease of use of this plugin, but sadly, it doesn’t work. It shows conversions, but my Aweber stats are different. So, either the emails aren’t feeding through to my Aweber account, or it’s miscounting conversions. I posted in the support forum looking for assistance, and have heard no response, (it’s been nearly 3 months.) I wish I could give it a better rating, but it pains me that I’m getting sign ups that don’t actually go through to Aweber. Kinda defeats the purpose.

IT’s a very good plugin for a free version of it. Simple to use and responsive.

It works right of the box. Pretty simple to use and some nice features for a free app. I am considering buying the pro version. It may not have all the bells and whistles, but I will tell you what… I bought a popup plugin with all the bells and whistles and it was soooo buggy. Optin Cat is clean. User friendly and has some pretty nice looking popups. I highly recommend it. Great value. Thanks.

I hardly ever do reviews of plugins, but I want to save you time and trouble…. this plugin is not good – and when I tried to deactivate it – it crashed my site. After 45 minutes with my hosting company, it’s finally resolved.

Hi, I upgraded to Optin Cat Elite because I loved the free plugin so much. I was disappointed with the 2-step optin, it wasn’t what I was expecting. Make an option for the Post and Sidebar forms to be a proper 2-step and this plugin will be perfect. Get it guys and upgrade!
