What is email authentication and why is it important for deliverability?

Email authentication is a process that verifies the sender's identity, helping to prevent spam and phishing. It's crucial for deliverability because it increases the chances of your emails reaching the inbox instead of the spam folder.

What are the main methods of email authentication?

The main methods include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance). Each plays a role in verifying the sender and ensuring email integrity.

How can I implement these authentication methods?

You can implement SPF by adding a specific DNS record, DKIM by generating a key pair and adding a DNS record, and DMARC by creating a policy that tells receiving servers how to handle unauthenticated emails.

What impact does email authentication have on my email marketing campaigns?

Proper email authentication can significantly improve your email deliverability rates, enhance your sender reputation, and increase engagement with your audience.
