Warmup planning
Email Warmup Planner
Plan a cautious cold email warmup ramp by mailbox age, daily send volume, reply quality, bounce risk, and weekly volume increases.
Direct answer
An email warmup plan gradually increases daily sends while watching bounce, complaint, reply, and placement signals. A safe ramp is slower for new domains, new mailboxes, weak lists, and unproven offers.
Warmup ramp framework
| Mailbox stage | Typical planning posture | What to monitor |
|---|---|---|
| New | Start low and increase slowly | Authentication, bounces, replies, complaints |
| Warming | Increase only when signals remain stable | Reply quality and list source by segment |
| Established | Keep volume consistent | Trend changes and fatigue |
What warmup can and cannot do
Warmup can create a more gradual sending history. It cannot make an irrelevant list, misleading offer, or spammy copy safe.
Use warmup as one part of launch readiness, not as permission to ignore list quality or consent rules.
When to pause the ramp
Pause increases if bounce rate rises, complaints appear, positive reply rate falls sharply, or inbox placement indicators weaken. A paused ramp is cheaper than burning a domain.
Checklist
- Authenticate the domain first.
- Start with verified and relevant contacts.
- Increase weekly, not randomly.
- Track replies and complaints.
- Pause if risk signals worsen.
