How to clean up messy CRM data after importing

Messy CRM data filled with duplicates, bounced emails, and outdated custom fields usually happens when a portal is set up without defined hygiene processes or team alignment. This clogs up reports and forces teams to repeatedly clean the database by hand every few months as bad data keeps flowing back in.

“I keep running into this one on a client account. A rep needs a second deal for someone they've already sold to, doesn't realize one contact can have more than one deal, so they make a whole new contact using plus addressing on the same mailbox to slip past the duplicate check.”source ↗

“Now there's three of the same person in there. The history is split across all three, every report by contact is wrong, the emails count separately, and they end up on different lifecycle stages with different deal stages.”source ↗
