1) Set safe sending limits
Limits help prevent accidental over-sending.
- Configure daily and hourly limits on each domain.
- Start low for new domains and raise gradually.
- Avoid sudden large increases between days.
- Adjust limits only after stable log outcomes.
2) Warm-up operating pattern
Warm-up is a gradual trust-building process.
- Begin with low daily sends.
- Increase in small steps when outcomes remain stable.
- Pause increases if failures or complaints rise.
- Use log trends to guide next-day changes.
