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Messy CRM data filled with duplicates, bounced emails, and outdated custom fields usually happens when a portal is set up without defined hygiene processes or team alignment.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.

Unedited, most upvoted first, each linked to the thread it came from.
“Once we scaled outbound, the issues showed up fast. Duplicate companies, contacts attached to the wrong accounts, missing or stale titles, inconsistent lifecycle stages, and reps editing records just to get sequences out.”source ↗
“I’ve been working on lead routing in HubSpot and keep running into this issue where phone numbers looks fine in the CRM, but arent really usable for the sales team.”source ↗
“Some numbers are incomplete, some are formatted wrong, and some looks totally normal in the contact record but dont actually connect when a rep tries to call.”source ↗
“The annoying part is, the contact still gets sent to Sales like everything is fine. Then the rep only finds out theres a problem when they actually try to reach them.”source ↗
“It's tough when only a few reps take database hygiene seriously”source ↗
“The amount of clients ive on-boarding that have 10k+ contacts that have bounced several times over, are test emails, are people that clearly do not and will not ever be interested in their services , or just plain invalid emails - all being recycled in email campaigns over and over again is MADDENING”source ↗
“I could use help cleaning up my database…”source ↗
“My team struggled with outdated custom fields clogging up reports.”source ↗
“Biggest headache for us now is keeping everyone aligned on updating deal stages consistently.”source ↗
“I ran into this same mess when we scaled outbound last year. The duplicate records were the worst part because reps would just pick whichever company object loaded first, and suddenly you've got three versions of the same account with different deal histories.”source ↗
“I have a unique instance we're struggling to work through and was hoping someone might have ideas.”source ↗
“How do we get sequence activity to log to the correct SF record? How can we say enroll John in Sequence 1, and then that activity should go to John / Webinar / Product A (Lead Status: Open) and not a different one?”source ↗
“It is so frustrating that our SF is configured with multiple records for the same person. It's such a nightmare to manage.”source ↗
“I just exported the customer list to excel and removed the customer's ID, but I can't seem to import a bulk customer in QB Desktop.”source ↗
“how to clean up the data is already imported tho there? im wotking for a company and they have uswd agencies before and now like there are 3 duplicates of same status label on their data. how to find all of this and clean up?”source ↗
“We had the same problem. Cleaned everything up, felt good about it, and three months later the CRM was a mess again because dirty contacts kept coming in through forms.”source ↗
“Im a fresher to admin role, please guide me how you did this cleanup.”source ↗
“reps who were fine keeping things tidy at 20 deals a month start dropping stages, leaving tasks open, or skipping the deal value field once they're juggling 100+.”source ↗
“Manual cleanup gets annoying fast.”source ↗
“Curious how others deal with this — I've inherited (and cleaned up) a few HubSpot portals now that had years of neglect: dead workflows nobody remembers building, duplicate/unused properties, broken lifecycle stages, lead scoring that was turned off and forgotten, orphaned lists still eating contact limits.”source ↗
“Is there anything you *still* haven't fixed because it's too tedious/risky to touch?”source ↗
