Why It Matters for Sender Reputation
The process of verifying that an email was actually sent by the domain it claims to be from, using protocols like SPF, DKIM, and DMARC. 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 authentication (email) is critical. A misconfiguration or oversight in this area can lead to decreased deliverability, increased spam filtering, or even blacklisting.
