Frequently Asked Questions

What is data validation?

Data validation verifies that data meets defined standards for accuracy, completeness, and format. In B2B, this typically means checking email deliverability, phone number validity, mailing addresses, and company information.

Why is data validation important for sales teams?

Invalid data wastes sales time, hurts email deliverability, and increases costs. Bounced emails damage sender reputation, wrong phone numbers waste calling hours, and bad addresses waste direct mail spend.

What tools validate B2B data?

NeverBounce and ZeroBounce are popular for email validation. Fullcontact and Clearbit validate and enrich contact data simultaneously. Most enrichment tools include some validation capabilities.

How often should you validate your CRM data?

Best practice is to validate data on entry (real-time validation) and run bulk validation quarterly. B2B contact data decays at roughly 30% per year due to job changes, company moves, and email changes.
