Database Hygiene Before a HubSpot Migration: Start with Email
In HubSpot, email is the unique identifier for contacts.
If you’re planning a migration to HubSpot, now is the time to clean your database — especially by reviewing contacts that don’t have an email address. Removing incomplete records can free up valuable space for contacts with full, usable data.
How to identify them:
In your current database, create a contact-level filter: Email does not contain “@”
This will generate a list of records without valid email addresses. Export and archive them for safekeeping, then remove them from your active database.
But don’t just delete and move on — there’s opportunity here.
Before purging:
• Assign someone to research and populate missing fields where possible.
• Enrich records using data tools.
• Partner with a lead generation provider to backfill your database strategically.
The goal? Maximize your contact capacity while maintaining data quality.
Remember: there will always be natural attrition in your database. Strong database hygiene ensures you’re making room for the right records — not just more records.
Clean data isn’t just an operational task. It’s a growth strategy.
