What is a domain reputation?

Domain reputation is a measure of the trustworthiness and credibility of a domain based on its sending behavior and overall online activity. Email providers and spam filters use domain reputation to determine whether emails from a specific domain should be delivered to the inbox, sent to the spam folder, or blocked entirely. Factors that influence domain reputation include spam complaint rates, bounce rates, engagement levels (like opens and clicks), and the presence of proper email authentication protocols (SPF, DKIM, and DMARC). Even if you use different IP addresses, your domain reputation follows you, making it crucial to maintain good sending practices. A strong domain reputation ensures better email deliverability and helps build trust with both email providers and recipients.
