We’ve upgraded our algorithms to automatically detect and isolate low-quality or abusive accounts to maintain high deliverability and protect warmup performance for all users.

Accounts with suspicious behavior - like connecting too many low-quality IMAP/SMTP accounts - are now moved to separate, isolated pools.

This ensures our main pool remains healthy for everyone else.

We run continuous monitoring and cleanup processes multiple times a week to enforce this.

This upgrade is already working behind the scenes to significantly improve pool integrity and warmup results across the board.
