- Protect your primary email address, which is connected to e.g. online banking services, job applications or business communication, and use a second or third address for everything else.
- Install a spam filter in combination with phishing and virus protection – your freemail provider generally offers this for free.
- Never open email attachments from unknown senders.
- Avoid allowing unknown senders to receive a confirmation of email delivery or the opening of an email, e.g. through automatic Out-Of-Office notifications.
- Deactivate the delivery of HTML emails in your email program. This will e.g. prevent cookies from being downloaded.
- Do not write your email address in plain text in the Internet, e.g. in guest books, blog comments or online forums.
- If it is not entirely necessary to provide your email address, then do not do it.
- Do not answer spam emails, even if there is an unsubscribe link.
- Do not klick on links in emails, because this allows your email address to be checked, and your will receive even more spam in future.
- Sender addresses are easy to manipulate – check whether the receiver matches to the email address.
- Serious offers and products are not advertised through mass mailings full of typing mistakes.
