It is not cluttered with advertisements and has had no technical glitches. I would highly recommend it to anyone looking for the most reliable web based e-mail service. Nice look to service, but poor functionality. The logging out process is a bit strange, but overall, a great site. The ProLaunch service will reward you for browsing certain web sites by giving you points that can be redeemed for cinema tickets, travel etc.
ProLaunch members receive their own free web-based email account.
Membership is free, but limited to residents of the US and Canada. They have a real problem downloading POP3 mail. I don't have to do that on any of the other web-based accounts. Needless to say I won't be using ProntoMail any more. I had read good things about Prontomail on this sight and decided to try it for myself.
