Why It Matters for Sender Reputation
A DMARC policy (p=quarantine) that tells receivers to treat unauthenticated email as suspicious. 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 quarantine (dmarc) is critical. A misconfiguration or oversight in this area can lead to decreased deliverability, increased spam filtering, or even blacklisting.
