Are brand-new domains treated equally?

New domains face heightened scrutiny compared to established ones. Like new ships requiring inspection before entering ports, fresh domains lack reputation history and must prove themselves through behavior before earning full trust.

New domain challenges: no sending history means filters apply conservative defaults, sudden volume spikes trigger warnings, authentication setup problems become more damaging, and any early complaints disproportionately affect limited reputation data.

What helps new domains: proper warmup starting with small volumes to engaged recipients, flawless authentication from day one, extremely clean lists with **confirmed opt-in**, and patience allowing reputation to build over four to eight weeks. Treat the first month as probationary period requiring extra care.
