HubSpot Deduplication, Done Properly
HubSpot dedupes on email and domain automatically. Everything else is a process you have to own.
What HubSpot does on its own
Contacts are deduplicated on email address and companies on domain, at creation and on import. If a record arrives with a matching key, HubSpot updates the existing record instead of creating a second one.
That handles the majority silently, which is exactly why the duplicates you can see are the awkward ones: the same person with a second address, the same company with a second domain, or records created by an integration that had no key to match on.
A deduplication process that holds
Clean what exists
Work the duplicate management tool for contacts and companies, merging the clear pairs and dismissing false positives so the list stays useful.
Close the source
Fix the forms, imports and integrations creating duplicates: require the work email, add secondary domains to companies, and give imports a matching key.
Cover the objects the tool ignores
Tickets and deals need their own approach. Tickets are the urgent one, because a duplicate ticket costs agent time the same day it arrives.
Frequently asked questions
Does merging in HubSpot lose the customer replies?+
No. Ticket Merger uses the native HubSpot merge, so the conversation, attachments and audit history move onto the surviving ticket. The duplicate is closed with a note pointing at the original.
Can I review merges before they happen?+
Yes. Start in suggest-only mode: Ticket Merger flags the pairs it believes are duplicates and leaves the decision to an agent. Most teams run that way for a week, check the hit rate, then let the confident matches merge on their own.
What stops it merging two tickets that are not the same?+
Rules you set. Match on requester, subject similarity, body similarity and a time window, and exclude anything you want left alone, like tickets from a specific form, group or tag. Anything below your confidence threshold gets suggested rather than merged.
How long does setup take?+
About five minutes to connect, and the first scan of your open queue runs immediately after. Onboarding help is included on every plan.
Deduplicate your tickets too
Ticket Merger applies the same idea to the service side, automatically, as tickets arrive.
