The Merge Contacts feature helps you combine duplicate contact records into one clean profile. When you merge contacts, you choose one primary contact to keep, and the selected duplicate records are merged into it.
Important: Merging cannot be undone. Always confirm that the correct primary contact is selected before you merge.
LeadCenter can flag contacts as possible duplicates when they share the same primary email or primary phone number. When duplicates are found, you can review them and merge them into a single contact record.
Note: Contacts that are linked as family/household members, primary contacts, or professional contacts may be excluded from duplicate detection even if they share the same primary email or primary phone.
During the merge:
There are three ways to open the merge page:
If the contact has been flagged as a possible duplicate, you may also see a warning banner at the top of the contact details page linking you to the Duplicates tab.
Tip: All three options open the same merge page. The contact you start from is set as the primary contact by default. If needed, you can change the primary contact on the merge page using Make primary contact.
When contacts are merged, LeadCenter moves related activity and records from the duplicates into the primary contact, including:
LeadCenter also brings over unique contact details from the duplicate, such as additional email addresses, phone numbers, addresses, websites, and social links.
LeadCenter keeps the primary contact’s main profile details. The duplicate contact’s versions of these fields do not replace the primary contact:
For custom fields, if the primary contact’s field is empty and the duplicate has a value, LeadCenter uses the duplicate’s value. If both have values, the primary contact’s value is kept.
Important: The duplicate contact’s versions of the fields above are not preserved in a way you can recover from the UI after the merge. If you need to keep any of that information, make the correct record the primary contact before merging, or copy the values you need first.
When you merge contacts, LeadCenter keeps the most restrictive marketing opt-out settings on the surviving primary contact. This helps make sure unsubscribe and opt-out preferences are still respected after the merge.
The rule is simple: if either contact has an opt-out enabled, the primary contact keeps that opt-out enabled after the merge. A merge never removes an existing restriction.
| Toggle | Merge Rule |
|---|---|
| Don’t call | If either contact has it ON, the primary contact keeps it ON |
| Don’t email | If either contact has it ON, the primary contact keeps it ON |
| Don’t mass email | If either contact has it ON, the primary contact keeps it ON |
| Do not mail | If either contact has it ON, the primary contact keeps it ON |
| Don’t mass mail | If either contact has it ON, the primary contact keeps it ON |
| Do not text | If either contact has it ON, the primary contact keeps it ON |
| Don’t mass text | If either contact has it ON, the primary contact keeps it ON |
| Do not invite | If either contact has it ON, the primary contact keeps it ON |
Some opt-out fields can become locked when a contact unsubscribes through an email unsubscribe link or sends STOP by text. If either merged contact has a locked opt-out field, the primary contact keeps that field locked after the merge.
Example: If the primary contact has Don’t email enabled, and the duplicate contact has Don’t call and Don’t mass email enabled, the merged contact will keep all three restrictions after the merge.
If one of the duplicate contacts is linked to Redtail or Wealthbox, LeadCenter shows a warning before the merge.
When you continue:
Note: You do not need to disconnect Redtail or Wealthbox before merging. LeadCenter handles the duplicate contact’s CRM disassociation during the merge.
If the duplicate contact is part of a household, LeadCenter updates household relationships automatically as part of the merge. This can include transferring spouse references, adjusting head-of-household roles, or moving remaining family members to the surviving contact’s household when needed.
When a merged contact is part of a household, LeadCenter follows these rules:
Suppose you have:
If you merge John Smith into James Wilson:
Important: This automatic reassignment prevents children and other dependents from being left behind in a household with no head of household after a merge.
The merge can be blocked if a selected duplicate has:
If that happens, resolve the issue first, then retry the merge.
No. Merging is permanent and cannot be undone.
Yes. You can select multiple duplicate contacts and merge them into the primary contact in one action.
No. The external CRM contact is not deleted. Only the duplicate’s connection from LeadCenter is removed.
No. The primary contact’s Redtail or Wealthbox connection stays in place.
It may. After a merge, the primary contact is updated, which can trigger workflows or other automations that run on contact updates.
