Why It Matters for Sender Reputation
An email authentication protocol that builds on SPF and DKIM to give domain owners control over how unauthenticated email is handled. Understanding this concept is essential for maintaining good email deliverability and protecting your domain's sender reputation.
How It Works
Email authentication protocols work together to verify sender identity and protect against spoofing. Proper implementation directly improves your Sender Reputation Score and inbox placement rates.
Practical Example
When configuring your email sending infrastructure, paying attention to dmarc is critical. A misconfiguration or oversight in this area can lead to decreased deliverability, increased spam filtering, or even blacklisting.
