Can Gmail delisting requests guarantee recovery?

No. Gmail does not have a delisting request process that guarantees recovery. Reputation improves through demonstrated good sending behavior over time, not through requests.

Google provides postmaster tools for monitoring but not for requesting delisting. Recovery requires fixing issues and maintaining good practices until reputation improves.

Focus on addressable factors: authentication, list quality, engagement, content. Reputation recovers as these improve. There is no shortcut through delisting requests.
