Email authentication is a method of verification that allows an email client to understand whether an email is actually from you or your business. It’s like a signature when an email is delivered, and alone can improve deliverability.
Spammers and phishers take advantage of the low level of security behind emails. They can pose as banks and corporate companies to steal money or spread malicious software. Not only does this harm the recipients of these scam emails, it also harms the companies that have been impersonated.
Large email clients such as Gmail, Outlook.com and Yahoo use email authentication to help determine if something is spam and should be blocked as a method of protection. As such, any unauthenticated email, no matter how legitimate the content, runs the risk of ending up in someone’s spam folder.
Normally it’s as simple as modifying some DNS records attached to a domain name you’re using. Authenticating this way improves deliverability, as you are properly stating your identity to recipient mail servers.
If you haven’t authorised your email marketing system to send email on your behalf, many email clients flag the email as coming from a different server, which can potentially cause the email to be blocked meaning they’ll lie in spam folders.
Outlook 2016, for example, will display in the recipient’s inbox as being “sent by” someone else. The email is sometimes then also sent to the junk folder as a result of the sending domain not being authenticated. This won’t happen every time — unauthenticated mail may still be delivered to the inbox. Gmail uses the word “via” to indicate an email hasn’t had its sending domain authenticated, whereas Outlook.com uses the phrase “on behalf of:”.
