6. Your emails are marked as spam: 10 signs you should invest in your personal cyber security

6. Friends report that your emails are marked as spam or that they receive unsolicited emails from you or that your emails never reach them

Antispam services use the reputation of a domain and email address to detect if it sent spam at some point. If the reputation is low, then there is a danger that
the emails sent from that domain/email address will be marked as spam. Depending on the configuration of the filter, the emails might be marked as spam, delayed, moved to spam folder or not delivered at all.

The best way to prevent something like this to happen to your email address and domain is to regularly monitor who accessed your account and keep a close look on the Sent items to see if there is something sent without your approval.
It is also important to enable two-factor authentication in order to prevent unauthorized access to your account.
