How to Merge Duplicates in Zendesk Sell
Merge duplicates in Zendesk Sell and prevent future clutter with LinkZen, ensuring your pipeline stays clean and accurate.
Published on September 9, 2025
Duplicate contacts are a daily headache for anyone managing sales pipelines in Zendesk Sell. They clutter your data, confuse your outreach, and can even tank sales efficiency by causing your team to work the same lead twice. In this guide, we’ll walk through how to spot, merge, and—most importantly—prevent duplicates in Zendesk Sell. Along the way, we’ll share why investing in clean, verified data from the start (with tools like LinkZen) saves hours of cleanup and stress down the road.
Why Duplicates Hurt Your Sales Process
Duplicates aren’t just annoying—they’re costly. Here’s why:
- Wasted time: Reps might reach out to the same contact more than once, hurting your brand and wasting precious selling hours.
- Split intelligence: Important communications and notes can end up scattered across several profiles.
- Reporting confusion: Pipeline numbers get inflated or deflated, leading to misleading metrics.
Duplicates happen for many reasons:
- Manual entry mistakes (typos, inconsistent data)
- Multiple team members entering the same lead
- Bulk imports from different sources
- Inconsistent formatting between records
The more team members or integrations you have, the greater the risk. That’s why having a clear duplicate management strategy is critical for US-based businesses aiming for data-driven sales success.
Identifying Duplicates in Zendesk Sell
Zendesk Sell provides a straightforward way to spot duplicates:
- Smart Lists: Use Smart Lists on your Leads or Contacts tabs. Filter by fields likely to overlap (like email or phone number) and visually scan for matches.
- Table or Index Views: Scan or sort columns to detect identical or highly similar entries in your Contacts/Leads.
- Manual Search: Search for key terms, domains, or names to reveal possible overlaps.
Zendesk Sell does not automatically flag duplicates, so it’s wise to schedule regular data review sessions.
Step-by-Step Merging Process
Ready to merge? Here’s how you do it in Zendesk Sell:
- Navigate to Leads or Contacts. Use the Index or Table view.
- Select Duplicate Records. Click the checkboxes next to the duplicates you'd like to merge (Zendesk Sell allows merging up to 5 at a time).
- Click the Merge Button. This shows up at the top of the screen when multiple records are selected.
- Choose Your Primary Record. The topmost selected record becomes the master record. Other data merges into this one.
- Resolve Conflicts: When fields differ (like two distinct phone numbers), Zendesk Sell creates additional custom fields to retain all non-identical information. Review and clean up unneeded fields after merging.
- Confirm Merge. You’ll get a prompt—click Confirm to combine the records.
Remember: You can only merge leads with leads and contacts with contacts. Leads cannot be merged into contacts, though they can be converted if needed. Additionally, you can’t merge person contacts assigned to different companies.
Bulk Duplicate Management
Dealing with dozens (or hundreds) of duplicates? Zendesk Sell’s merge feature supports batch merging:
- Select up to 5 records at once to merge.
- Use Smart Lists to find and group similar records quickly.
- After merging, review your custom fields for redundant data.
For large data sets, repeat this process in manageable chunks to maintain accuracy.
