What’s the danger of premature domain changes?

Wasted reputation:

• Even damaged reputation has some value
• New domain starts from zero
• Recovery may have been faster than restart

Warmup delay:

• New domain needs full warmup
• Cannot send at volume immediately
• Business disruption during warmup

Spammer signal:

• Frequent domain changes are spam pattern
• Providers may be suspicious of new domains
• History of changes follows you

Problem repetition:

• If root cause not fixed, same problems on new domain
• Just delays the issue
• Wastes the new domain too
• Fix problems before considering domain changes.
• Abandoning a ship before trying repairs wastes resources and looks suspicious.
