Domain Reputation
Domain reputation is the trust score that mailbox providers (Gmail, Outlook, Yahoo) assign to your sending domain. Unlike IP reputation, which is tied to the sending server, domain reputation follows your brand across infrastructure changes. It is influenced by authentication setup, complaint rates, bounce rates, spam trap hits, and recipient engagement.
Domain vs IP Reputation
Historically, IP reputation was the primary signal. Today, domain reputation matters more because:
- ●Domain reputation persists across IP changes
- ●Major providers (Gmail, Yahoo) weight domain reputation heavily
- ●DMARC, SPF, and DKIM all tie to the domain, not the IP
- ●Cloud infrastructure uses shared IPs, making domain-level tracking essential
Protect your domain reputation by maintaining clean lists, proper authentication, and consistent sending patterns.
