Sender Reputation

Every email that leaves your domain contributes to its reputation — for better or worse. Email providers like Google and Microsoft maintain sophisticated models that evaluate sending behavior across multiple dimensions: how many recipients mark your emails as spam, how many bounce as undeliverable, how many are immediately deleted without being opened, and how many actually receive replies. Over time, these signals accumulate into a reputation score that directly controls where future emails from your domain land. The most damaging actions for sender reputation are sending to purchased, outdated, or low-quality contact lists that generate high bounce and spam complaint rates; sending high volumes too quickly from a new domain; using deceptive subject lines or misleading sender names; and failing to honor unsubscribe requests. Conversely, the most beneficial actions are maintaining a clean, verified contact list, sending to engaged audiences who open and reply to messages, warming up new domains properly, and using authentication protocols (SPF, DKIM, DMARC) correctly. Personalized video outreach from Outvid has a positive secondary effect on sender reputation. Because video emails generate higher open rates, click rates, and reply rates than generic text emails, the engagement signals they produce tell email providers that your messages are wanted. Over time, this creates a virtuous cycle: strong engagement reinforces a strong reputation, which ensures continued inbox placement, which maintains high engagement rates.
