My experience matches what I've read here. This is a great layer of privacy to email, something that people may not get at first. As others pointed out, with this kind of service, you will know who's selling your data, and to whom (knowing allows you distance yourself from companies that choose such practice). So, I've been using AnonAddy for a little over five months now (since they launched the service, I believe) and I'm very happy with it. Support just works, as every time I contacted them I got a reply that was actually helpful (nothing of that generic replies I see in other services I subscribe to - services that, because of such behavior, will get replaced soon). My experience has been so smooth up to the point I'm switching to AnonAddy (from a service I've been using in the last 5 years). Bottom line: It's reliable (have not seen "MIA" emails for instance), has great support, and the platform seems flexible enough to accommodate new functionalities (yes, there's room for improvement here and there, and that's a good thing really). Thank you for building this, and wish you all the success!
