What is a “clean-slate” approach (new domain or subdomain)?

A clean-slate approach abandons severely damaged sending identities and starts fresh:

Register a new domain or subdomain with no sending history. Configure new authentication records. Begin the full warmup process from zero.

This approach makes sense when existing reputation is so damaged that recovery would take longer than building fresh. Some reputations are effectively unrepairable.

Risks include inheriting suspicion if providers detect organizational relationships between old and new domains. You cannot simply rename your way out of problems.

Requirements include genuinely fixing whatever caused the original damage. A clean slate with the same bad practices just creates another damaged domain.

Clean-slate is like scuttling a damaged ship and commissioning a new one. It only works if you also retrain the crew. Putting the same captain on a new vessel repeats the disaster.
