Our service significantly reduces the amount of spam you receive without installing any software on your computer. That's because we filter the spam before you download it. Our system recognizes the spam, sets it aside, and lets you download only the email you want to receive.

Your email address will not change, nor do you need to open a new email account.

We do this by putting our server between your computer and your mail server. When your computer asks our server for your email, we in turn ask your email server for your email. Once we get your mail, we filter spam and unsolicted email into a "holding area". Non-spam is seamlessly downloaded to your email program.

How it all works

When you first sign up with our service, you will have an array of SPAM filters at your disposal. These filters are designed to block the vast majority of SPAM while we 'train' our Bayesian Filter to your useage.

Since everyone's email habits are different, our 'normal' filters can be turned on and off by you at a granular level letting you customise the filtering ensuring the most spam is blocked, with the least false-positives.

False-positives are mails that we thought were spam, but actually were legitamate. To combat this, we (optionally) send you a mail once a night describing the mails we've filtered in the last day. If there are any legitamate mails that have been filtered, you can click on a link, and they will be downloaded the next time you check your mail.

Conversely, if a spam message gets through our filters, there is a link that you can click to report that mail as spam. We use this report to tune our Normal Filters as well as automatically train our Bayesian Filter to your email profile.

Once your get a 'corpus' of emails (approximately 50 good and 50 bad mails), we'll ask you if you'd like to turn on Bayesian Filtering. This will be tuned off of your previous activity, and will catch much more spam with fewer false-positives.

The Spam Problem
With the good comes the bad. Today, our email inboxes are clogged with unwanted, unsolicited emails. In the early days, spam wasn't a problem. It is today! PrismEmail can help.
ISPs and our system
Most "normal" ISP email accounts and email clients will work with our service.
Privacy and Security is key
We know that an anti-spam service that helps to improve your privacy is of no use if the service itself were to abuse your privacy. In addition, our service was designed from the ground-up to ensure that no customer information remains on any Internet-accessible server.
