Works really well and does everything it promises. The only glitch is that some websites won't accept the "@simplelogin.com" domain. If that happens, try the alternate "@slmails.com". Or try the "totally random alias" feature that omits the website name from the alias. I don't know how the websites are screening SLMAILS. Do they have a way to check for valid email addresses in real time? If that is the case, it may be necessary to use an alias that you already created some minutes ago, or used at least once before.
