Domain Reputation
The sender domain's trustworthiness.
Domain reputation is a measure of how trusted an email sender’s domain is by ISPs. Factors affecting domain reputation include engagement metrics (opens, clicks), spam complaints, bounce rates, and list hygiene. A poor domain reputation can result in emails being sent to spam folders or blocked entirely. Regularly monitoring reputation and implementing best practices—like using authentication protocols (SPF, DKIM, DMARC) and avoiding spammy behavior—ensures reliable inbox placement and protects the sender’s credibility.
