SpiffyPost offers completely free web-based access to your existing POP or IMAP email accounts. Premium features, such as an address book and calendar, are at your disposal. Unlike other services similar to this, no ads are placed on outgoing emails so it makes this a perfect companion whether you're at your normal computer or not. Furthermore, no registration is necessary.

By default, the login will access your email account via POP. Please select "Advanced Login" if wishing to use IMAP, and/or if your email account uses your full email address as the username. Also, the "lite" version (for PDAs, etc) can be accessed at http://www.spiffypost.com/pda/.
