How long do sending domains last, and how often should I rotate them?

Updated Nov 6, 2026

It depends heavily on sending behavior:

With high complaints, bounces, or low reply rates — domains can burn quickly
With conservative sending and strong campaigns — domains can last many months or over a year

As a proactive baseline, ScaledMail recommends rotating domains every 3–4 months — or immediately when reply rates drop significantly from your baseline.
