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, and company firmographics such as industry, headcount and location 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. Every new workspace starts on Scale for 14 days with 250 credits, 3 seats and no card, then the Free plan is $0 for 30 credits a month and paid plans start at $79/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.
What are the best B2B data enrichment tools?
The best B2B data enrichment tools in 2026 include Cleanlist (waterfall enrichment with 25+ providers), Apollo (sales engagement + enrichment), ZoomInfo (enterprise data platform), Clearbit/Breeze Intelligence (HubSpot-native enrichment), and Cognism (European data strength). The best choice depends on your tech stack, budget, and data coverage needs. Cleanlist offers the most cost-effective multi-provider approach starting at $79/mo.
Which data enrichment companies are most reliable?
The most reliable data enrichment companies maintain large, frequently updated databases and verify data accuracy. Cleanlist achieves high accuracy through waterfall enrichment, querying 25+ providers and cross-referencing results. ZoomInfo and Cognism maintain large proprietary databases. Apollo combines its own data with community-contributed records. Reliability varies by data type and region, so testing multiple providers on your specific data is recommended.
Run one list through it.
