If an abuser has access to your e-mail account, they may be able to read your incoming and outgoing mail.

If you believe your account is secure, make sure you choose a password that an abuser will not be able to guess.

If an abuser sends you threatening or harassing e-mail messages, they may be printed and saved as evidence of this abuse. The messages may constitute an offence.

This information may not completely hide your tracks. Many browser types have features that display recently visited sites. The safest way to find information on the net, would be at a local library, a friend's house, or at work.
