How does domain age affect trust?

Domain age is a minor but meaningful trust signal. Older domains with consistent sending history have demonstrated stability over time. Providers have more data to evaluate and can make confident filtering decisions.

Newly registered domains face skepticism. Spammers frequently register fresh domains to avoid the baggage of burned identities. Providers compensate by treating new domains with caution until they prove themselves through clean sending over weeks or months.

Age alone does not guarantee good reputation. An old domain that suddenly starts sending after years of dormancy gets scrutinized nearly as heavily as a new one. What matters is the combination of age and consistent positive sending history.

Domain age is like years of service on a captain's record. Experience suggests competence, but a captain who retired decades ago and suddenly reappears needs to prove they can still navigate modern waters.
