Frequently Asked Questions
What is data enrichment?
+
Data enrichment is the process of enhancing existing records with additional information from external sources. For B2B teams, this typically means appending verified emails, phone numbers, job titles, company firmographics, and technographic data to your contact and account records.
How does waterfall enrichment work?
+
Waterfall enrichment queries multiple data providers in sequence for each record. If the first provider doesn't return a result (or returns low-confidence data), the system automatically falls back to the next provider. This dramatically improves match rates compared to relying on a single source.
How much does data enrichment cost?
+
Cleanlist uses credit-based pricing starting at $0/month with 30 free credits. Paid plans start at $49/month. Unlike legacy providers that charge per seat or require annual contracts, you only pay for the enrichments you actually use.
What's the difference between data enrichment and data cleansing?
+
Data enrichment adds new information to existing records (e.g., appending a phone number to a contact), while data cleansing fixes or removes inaccurate data (e.g., correcting misspelled company names or removing invalid emails). Most teams need both for a healthy CRM.
