Hi, we tried your plugin using the free license, but it failed to stop subscriptions using fake emails and disposal emails !!! we think that you need to perform it! good luck!

I was using AcyMailing for 2 years, when I heard that they were developing a new plugin: AcyChecker. What a surprise! AcyChecker is very useful, I wasn't aware that my database was so full of fake users. AcyChecker helped me clean my database efficiently. The interface and the features are really easy to understand and to use. If you want to improve your database. Jump on the occasion, you won't regret it!
