Summary
Improving a domain's email reputation from bad to good is a multifaceted process demanding consistent effort over time, without a definitive timeline. Experts, marketers, and documentation sources concur that the duration depends significantly on the severity of the initial reputation damage, the underlying causes (such as blocklisting, spam complaints, poor list hygiene), and the effectiveness of implemented remediation strategies. While some observe improvements within 3 weeks to 3 months, others emphasize it's a gradual journey, akin to building trust. Key actions include list cleaning, sending engaging content, authenticating email, managing bounce rates, and promptly addressing sending issues.
