Why schedule warming?
Major email providers expect gradual volume growth
Major email service providers track engagement rates and sending volume patterns to prevent abuse on their networks. A gradual ramp helps a dedicated IP with neutral reputation build sending history over time.
- Start from a conservative daily volume.
- Increase volume only as reputation and engagement stay healthy.
- Pause or slow down if bounces, complaints, or blocks rise.
