Generally defined, email authentication is a multi-method approach to securing email communications. Email senders create a public record which validates that their sending domain is authorized to send email from a particular IP address or mail server. ISPs and corporate email servers use this validation, along with other metrics, to determine if they trust the sender to deliver email to the inbox.
There are currently four different methods or standards that are typically used for email authentication:
Each standard authenticates using a different methodology. While a sender can authenticate using all of the standards, an ISP may choose to only verify one or more of them.
We monitor changes in ISP authentication practices and make ongoing adjustments to our protocols so clients always have the latest authentication methods at their disposal. All of this expertise is applied “behind the scenes” so clients just send their email, and then simply watch it hit the inbox.
Authentication is only part of the many steps we take to ensure top deliverability for your emails.
