Email authentication protocols are crucial for ensuring that your emails are delivered to your subscribers’ inboxes and not marked as spam. While many email marketers are familiar with basic authentication protocols like SPF and DKIM, there are more advanced protocols that can be used to improve deliverability even further.
Here are some advanced email authentication protocols that can help improve deliverability:
- DMARC: Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that builds on SPF and DKIM. DMARC allows email senders to instruct email providers on how to handle unauthenticated emails from their domains, helping to prevent email fraud and spoofing.
- BIMI: Brand Indicators for Message Identification (BIMI) is an email authentication protocol that allows brands to display their logos alongside their emails in subscribers’ inboxes. BIMI uses a combination of DMARC and a Verified Mark Certificate (VMC) to authenticate emails and display the brand logo.
- ARC: Authenticated Received Chain (ARC) is an email authentication protocol that allows intermediate email servers to authenticate an email’s message flow. ARC helps to prevent authentication failures that can occur when emails are forwarded or redirected by intermediate servers.
By implementing advanced email authentication protocols like DMARC, BIMI, and ARC, email marketers can improve their email deliverability and prevent fraudulent emails from being sent from their domains. Additionally, using these protocols can help improve brand trust and recognition by allowing brands to display their logos alongside their emails in subscribers’ inboxes.
