Great hunt @emrebeyler!

The following text is my opinion about this product, I'll write down the things that I like or dislike about it.

It's a great idea of a service, having a mask or more that will redirect only the mails you need to your main mail. And if the service allows some filtering too it's even better.

Pros:

• you can try it for free before buying it, free you get 10 maskmails but if you pay the 10$/year you get unlimited maskmails
• great idea of a service
• they have their own extension that can be used as a shortcut to create maskmails
• easy and intuitive UI, anyone can use it

Cons:

• nothing, it's a great service
