Semi-OT. Having a b2c startup I have mixed feelings on this kind of services.

I totally value privacy (and security) and I support the existence of services like this one, even thought -as a user- I don't completely understand the difference between creating a random gmail address. The user's pain is usually related to change the address (i.e., notify all my friends), so a service like this one should actually resolve that pain specifically, IMO.

On the other hand, I also think this creates a mess with other businesses. Users register to services using username+password that they inevitably forget. If you just put the signup with Facebook + Twitter + Google, they complain that you're requiring a social account. Even if they don't complain, the sign up with Google and later they try to sign in with Facebook. In short, the email is the only way to come back via password reset. But what if they can no longer access the email they used to sign up?

One of the advantages of Mailinator and 33mail (two other services in this space) is that they allow you to receive email at your aliases for as long as you want, so they don't preclude password recovery. I think this service is somewhat hamstrung by the limited period when the temporary address is accessible.

There is no limit after registering the address. The idea was to cover temporary needs as well as providing the posibility to use it persistently.
