DodgeIt allows you to check disposable email addresses on the fly (without having to create one) to avoid possible spam that comes with signing up for new services.
When you sign up for an account, DodgeIt allows you to enter any name @dodgeit.com as your email address. Afterwards, visit DodgeIt.com to check that disposable email address, even though you didn’t go through the process of creating it. DodgeIt also provides you with an RSS feed for each email address to keep an eye on your throwaway email address.
Because you don’t have to create accounts, keep in mind that anyone can check that email address at any time, so don’t give the address out to friends or family. You can however make a small $2 donation and they’ll let you password protect your account and delete emails too.
