If you’re looking for a little anonymity and security when signing up for download links or invite codes, a disposable email service is a good option. Instead of providing one of your working email addresses, just grab a meaningless temporary one from any of these sites and keep your identity hidden.
These four sites all provide RSS feeds for your address, which is quite useful. No need to return to the site after registration, just subscribe with your favorite newsreader.
MailCatch – Choose your own address or roll the dice. MailCatch also provides an iGoogle gadget and creates a sub-domain (using your address) for quick access to your web inbox. MailCatch also provides temporary forwards, and they’ve got an FAQ and forums.
MyTrashMail – Offers password protected temporary accounts in addition to the traditional public variety. Note that the Firefox “toolbar” they offer requires you have the Google toolbar installed first. FAQ and about links are prominently displayed.
Incognito Mail – The option for minimalists. Choose or generate your address, and it’s valid for 60 minutes. No FAQ or TOS is posted. There are a number of other services that look very similar to Incognito Mail, offering different time limits.
