Warmup equals reputation. Without it, inbox rate collapses and your sends land in spam.
1. Start with real interactions
Open, reply, and mark as important. Human activity matters more than bots.
2. Increase in steps
Go up 20% per week, not 300% in a day. Gradual growth is key.
3. Keep warmup running in parallel
Even once you are sending, keep warming to sustain reputation.
4. Avoid spikes and pauses
Spikes trigger alerts and abrupt pauses break your sending history.
Quick checklist
- Real replies every week
- Stepwise volume increases
- No long pauses
- Continuous warmup
