For some time now I’ve been using sharpmail.co.uk, a service which lets you send and receive anonomous email. If you are not sure whether that forum you are thinking of joining will sell your email address then Sharpmail is worth considering.
Sharpmail works like this. You sign up for a free account and can then create fake email addresses, consequently any email you send, from Sharpmail will show the disposable fake address rather than your main (permanent) address. So if you want to sign up with that forum just enter the address provided by Sharpmail and you will receive any mailings, from the forum to that address. You can either log into Sharpmail to retrieve and respond to your messages or, alternatively you can set Sharpmail to forward any messages to an email address specified by you. If you go for the latter option any replies to messages (sent to your Sharpmail address) will appear to come from that address rather than from your actual email account), consequently no one need ever know your real email address.
If your Sharpmail address starts to attract a lot of junk mail, no problem you can delete it easily safe in the knowledge that the spammer does not know your real email.
Sharpmail enables you to have a number of email addresses. Additionally you can set an expiry time/date on an email address so you can, for instance set up an address specifically to sign up for a forum with a short shelf life, reply to confirm your wish to join the forum and the email address you used to register is no more.
Emails sent using Sharpmail do not show your Internet Service Provider’s (ISP’s) details thereby making it almost impossible for spammers to trace you and bombard your account with junk.
