What is an outgoing email, and why is it important to secure it?
An outgoing email is an electronic message that you send from your own email address to one or more external email addresses.
Securing outgoing emails is just as important as securing incoming emails, for several reasons:
- Protecting your domain's reputation: Unsecured outgoing emails, such as those sent in bulk or containing suspicious links, can be flagged as spam by email providers, which can harm your domain's reputation and lead to blocks by certain recipients.
- Preventing account hijacking: A compromised email account can be used to send unauthorized outgoing emails, such as spam or phishing emails. Securing outgoing emails helps prevent account hijacking and protect your domain's reputation.
- Regulatory compliance: Certain sectors, such as healthcare or financial services, are subject to strict data security regulations. Securing outgoing emails can help you meet these regulatory requirements by ensuring the confidentiality and security of the information you send by email.
