Recovering a bad Gmail sender reputation and improving IP/domain rating is a complex and lengthy process, typically spanning several weeks to months, or even longer. Factors influencing the timeline include the severity of the initial damage, sending volume, list quality, and subscriber engagement. It's crucial to avoid committing to specific dates and instead focus on sustained good behavior, consistent engagement, and valuable content for subscribers.

Expert view
Expert from Email Geeks says to do something grossly over estimated. Like “if you focus on sending to engaged users consistently over the course of 6 months, I would expect to see that reflected in your reputation going from bad to poor. Another 6 months, and we can expect it to go to low”.

Expert view
Expert from Email Geeks says there’s no way to fix anything at Gmail sending 2 campaigns per month to unengaged leads. She suggests stopping mailing for a period of time to let the really bad reputation reset, and then focus on people who will go look in their spam folder and pull the mail out.
