The 14-day ramp
Checklist above. No cold email yet.
Your best-fit, verified contacts. Plain text, one link at most.
Only if bounces stayed under 2% and no complaints came in.
Your working volume. Keep 10-20% warmup traffic running.
Run a seed test. Compare reply rates by domain and rest any domain that trails.
What to watch
| Signal | Healthy | Act if |
|---|---|---|
| Hard bounces | Under 1% | Over 2%: stop and re-verify the list |
| Spam complaints | 0 | Any: pause that domain for 48 hours |
| Gmail spam rate (Postmaster Tools) | Under 0.1% | Over 0.3%: Google's hard line |
| Reply rate | Steady or rising | Drops by half on one domain: rest it |
If you send from Getlead, pre-warmed mailboxes connect as senders in one click and the ramp, warmup and per-domain health checks run automatically.
Questions people ask
How many emails should I send from a new pre-warmed mailbox?
Start at about 15 cold emails per mailbox per day in the first week and rise to 30 by the end of it, while keeping warmup traffic running in the background. Hold if bounces or complaints appear.
Should I change the passwords on pre-warmed mailboxes?
Yes. On handover, change the super admin password, set your own recovery email and phone, enable 2-step verification, then rotate mailbox passwords or app passwords before connecting your sending tool.
