Finding and merging duplicates
Open Manage Duplicates
In the Contacts section, click the three-dot icon in the top right corner and select Manage Duplicates.
Choose an identifier
Select the field to use for duplicate detection: Email, Phone Number, or Name.
Duplicate detection applies to primary email and primary phone fields only.
Review duplicate groups
The system generates a grouped list of duplicate entries matching your chosen identifier. Expand each group to view contact details and decide how to resolve them. Up to 10,000 duplicate entries are shown at a time.

Resolve duplicates
For each group, choose one of three actions:
- Reject — exclude the entry from future scans (for contacts that are legitimately different despite sharing a value)
- Review — open a detail view to compare records before deciding
- Merge — consolidate up to 10 records into a single master record
Merging contacts
When you select Merge, a comparison view opens for you to choose which data to keep.Designate a master record
Click the radio button next to the contact you want to use as the primary (master) record. Or click Select All from this column to automatically use all data from one contact and designate it as master.
Choose fields to retain
Select the data from each contact to keep. By default, only fields with differing values are shown. Enable All Fields to compare every available data point.
Configuring deduplication settings
Control how the system handles contacts that share the same identifiers during import.Adjust Contact Deduplication Preferences
Scroll to Contact Deduplication Preferences and configure:
- Allow Duplicate Contacts — when enabled (blue), new contacts can share identifiers with existing ones; when disabled, importing a contact with matching identifiers updates the existing record instead
- Primary and secondary search preferences — set the field priority for deduplication matching
Even with “Allow Duplicate Contacts” enabled, duplicates can still be created via forms or Zapier integrations. Use the Manage Duplicates scan periodically to keep the database clean.
Restoring deleted contacts
Accidentally deleted a contact? Hoop retains deleted contacts so you can restore them along with all their associated data.Open the Restore section
In the Contacts section, click the three-dot icon in the top right corner and select Restore.
Find the contact to restore
The deleted contacts list shows each contact’s name, email, phone number, and deletion date.

Access to the Restore section may depend on your user permissions. Contact your account administrator if the option is not visible.
Troubleshooting
| Issue | Possible cause | Solution |
|---|---|---|
| No duplicates found | Scan criteria too narrow | Try a different identifier: Phone or Name |
| Limit reached (10/10) | Too many records selected | Merge the first 10, then return for the next set |
| Merge button disabled | Confirmation not checked | Check the “I understand this cannot be undone” box |
| Missing merge option | User lacks Admin privileges | Contact your administrator to request access |
Auto-merge Facebook Messenger contacts with Lead Ad contacts
When a contact interacts with your business through both Facebook Lead Ads and Facebook Messenger, duplicate records can be created — one from the lead form submission and one from the Messenger conversation. The platform can automatically merge these records when a match is detected:- Matching logic — the platform compares the Facebook user ID, email address, and phone number across both records
- Auto-merge behavior — when a Messenger conversation is initiated by a contact who already exists from a Lead Ad submission, the records are merged automatically into a single contact
- Data preservation — all conversation history, lead form data, tags, and notes from both records are consolidated into the merged contact
- Verify that your Facebook integration is active and the correct pages are connected
- Ensure Lead Ad form field mapping is complete in Settings > Integrations > Facebook
- Keep the Allow Duplicate Contacts setting disabled in Settings > Business Profile
