Email Spam Blocker Software FAQs
Is scanning outbound emails important?
There are two important reasons to scan outgoing email. The first is to prevent spam emails from being sent from addresses on your domain. This is a reputation management issue because a high volume of spam will get all of the emails sent from your domain name filtered out as spam. The second purpose is for data loss prevention.
Can spammers tell if you open an email?
Some email systems include a read receipt notification option. However, the corresponding email clients of those systems also allow the recipient to block the sending of email opening confirmation while other systems, such as Gmail, only enable read receipt notifications between email addresses within its domain. A more common notification method is to include a tracking pixel in the email. When the recipient opens the email, the pixel loads from its home server, triggering a record that the email was opened. Recipients can prevent this notification process by setting a block on images loading in emails.
Can anti-spam software companies be trusted with my sensitive emails?
Anti-spam systems usually work as a filter. They don’t store emails on their own servers and so won’t compromise your privacy. Secure sensitive emails with end-to-end encryption to be sure that no proxy service can read the contents.
