Merge Contacts: Eliminate Duplicates and Clean Your Database

Merge contacts

Find and merge duplicate contacts to keep your donor data accurate, complete, and trustworthy.
Duplicate records clutter your database and lead to embarrassing double mailings, inaccurate reports, and missed giving history. DonorDock's merge tool helps you find potential duplicates and combine them into a single, complete record — preserving all gifts, activities, and notes.

Automatic Duplicate Detection

DonorDock scans your database for contacts with matching names, email addresses, or other identifiers and flags potential duplicates. Review suggested matches, confirm which records to merge, and DonorDock combines them into one clean record.

Preserve Every Detail

When you merge contacts, nothing is lost. Gifts, activities, notes, badges, and custom field data from both records are combined into the surviving contact. You choose which name, address, and email to keep as the primary — DonorDock handles the rest.

Bulk Merge for Clean Imports

After a data import, duplicates are common. DonorDock helps you clean up quickly by surfacing likely matches and letting you merge them in batches. This is especially valuable when consolidating data from multiple sources during a CRM migration.

Keep Data Clean Going Forward

DonorDock's duplicate detection runs continuously, alerting you when new records look like existing contacts. This prevents duplicates from accumulating over time and keeps your reporting accurate.

Frequently Asked Questions

Will merging contacts delete any data?
No. All gifts, activities, notes, and history from both records are preserved on the merged contact. You choose which primary details (name, email, address) to keep.

Can I undo a merge?
Merges cannot be automatically undone, so DonorDock shows you a full preview before confirming. Review all data from both records before proceeding.

How does DonorDock detect duplicates?
DonorDock compares contacts by name, email, phone, and address to find likely matches. The system suggests duplicates for your review — you always make the final decision.
