Why list hygiene matters
A bad list is expensive long before you notice the drop
Reputation is the hidden system behind every campaign result. Mailbox providers score your behavior over time, and low-quality addresses send the wrong signal quickly.
Sender IP trust erodes
Low-quality contacts can hurt shared or dedicated IP performance across future campaigns.
Inbox placement gets worse
Even strong campaign copy gets pushed into Promotions or Spam when reputation slips.
