What 30 days of Mailreach warm-up actually moved

A recruiter cold-starting a fresh Google Workspace domain ran Mailreach warm-up before any real sends. Tracked seed placement with GlockApps weekly.

Day 1: 71% landed in spam on a cold seed list.
Day 14: spam dropped to 22%.
Day 30: 4% spam, 89% primary inbox.

Then first live campaign of 400 sends held 84% inbox. Warm-up ramp: 4 emails/day to 40/day.

Pros
— Reply-and-archive behavior looked human in headers
— Auto-removes from spam, marks important
Cons
— $25/mailbox/mo adds up across a fleet
— Placement plateaus, won't fix bad copy

Verdict: 4/5. Warm-up is insurance, not a deliverability cure.

Who it's for: anyone spinning up new domains. Skip if your domain is 12+ months old with clean history — you're paying to warm an already-warm seat.
