What is email authentication?

Email authentication is a powerful tool that helps protect users from harmful phishing or spam emails. When an email is authenticated, it means that the email is coming from the source that it claims to be coming from. This is done through a few different authentication standards, such as SPF, Sender ID, DKIM, and DMARC. These standards work like a digital identification card, and help to protect your identity, brand, and reputation. Phishing scam emails often change the source of their origin, and change their design and feel to make it look like it is from a reputable brand or business. However, when an email is properly authenticated, it is much easier to spot these scams and protect yourself from them.
