Prospect Duplicate Detection: Data Quality Automation
You mention a prospect email in a Linear comment. Apollo should instantly show if they already exist in your database. Right now you manually search and duplicate entries pile up.
Trigger
Comment Received Trigger
Triggered when a comment is received.
Action
Search Apollo contacts
Searches apollo contacts using keywords, stage ids (from 'list contact stages' action), or sorting (max 50,000 records; `sort ascending` requires `sort by field`).
Why this helps
Prospects are created multiple times across teams because there's no instant visibility into whether they already exist in Apollo. Duplicate records fragment data.
- Duplicate prospects prevented instantly
- Teams know who already exists in Apollo
- Cleaner prospect database
- Better team collaboration
Setup
Build it in a few focused steps.
- 1Connect Linear and Apollo to Notis.
- 2Create an automation called 'Check for Existing Prospects'.
- 3Write: 'When a prospect email or name is mentioned in a Linear comment, search Apollo to check if that person already exists in your database.'
- 4Select 'Comment Received' as the trigger.
- 5Test by mentioning a prospect email in a Linear issue comment.
Questions about this workflow
What happens if a duplicate is found?
Notis reports the existing record to you. You can then decide to skip creating a new record, merge duplicates, or update the existing one.
How does matching work - email, name, or both?
Notis matches by email first, then by name if email doesn't exist. This minimizes false positives.
Can this be automated to prevent creation entirely?
Not automatically - human judgment is important. Notis reports the duplicate, and you decide the next step.
