How long does it take to fix a bad Gmail sender reputation and improve IP/domain rating?

Summary

The time it takes to fix a bad Gmail sender reputation and improve your IP/domain rating is rarely a fixed timeline. It is a dynamic process heavily influenced by user engagement, the severity of past sending issues, and the consistency of corrective actions. While some improvements might be seen in weeks, full recovery often spans months, depending on the sustained positive behavior and how deeply the reputation has been damaged. Understanding the factors at play and committing to long-term best practices is more crucial than adhering to a rigid schedule.
