Waterfall Enrichment: Stack Multiple Data Providers for Maximum Coverage
TL;DR
Waterfall enrichment queries multiple data providers in sequence for each lead, falling back to the next provider when one fails. Enrichabl's data enrichment waterfall maximizes coverage for email verification and AI enrichment while keeping costs low through the BYOK model. No single provider has complete data - waterfall enrichment closes the gaps.
What Is Waterfall Enrichment?
Waterfall enrichment is a lead enrichment strategy where your data flows through multiple providers in sequence. Instead of relying on a single source - and accepting whatever gaps it leaves - a waterfall approach queries Provider A first. If Provider A doesn't have the data, the system automatically queries Provider B, then Provider C, and so on until the data is found or all providers are exhausted.
This approach is standard practice among enterprise sales teams and data-driven agencies. Tools like Clay popularized the waterfall enrichment concept, but Enrichabl makes it accessible at a fraction of the cost through flat pricing and the BYOK model.
How Data Enrichment Waterfall Works in Enrichabl
Import Your Lead List
Upload a CSV of leads with whatever data you have - names, emails, company URLs, or just domains. Enrichabl maps your columns automatically.
Configure Your Waterfall
Choose which providers to use for each enrichment column and set the fallback order. For email verification, Enrichabl waterfalls through Bounceban and Mailveri. For AI enrichment, it can waterfall through OpenAI and Gemini.
Enrichment Runs Automatically
For each lead, Enrichabl queries the first provider. If the result is missing or low-confidence, it automatically falls back to the next provider in the waterfall. No manual intervention required.
Export Enriched Data
Download your enriched CSV with all waterfall results consolidated into clean columns. Every email is verified, every AI column is filled, and you have maximum data coverage across your entire list.
Why Waterfall Enrichment Beats Single-Provider Enrichment
Higher Data Coverage
No single data provider has 100% coverage. Waterfall enrichment typically increases email find rates by 20-40% by falling back across multiple providers.
Better Email Deliverability
Waterfall verification catches invalid and risky emails that a single provider might miss. Multi-provider validation keeps your bounce rate under 2%.
Lower Cost Per Lead
You only query additional providers when the first one fails. Combined with BYOK pricing and no per-lead fees, your cost per enriched lead drops significantly.
Automatic Fallback Logic
No manual work required. Enrichabl handles the waterfall logic automatically - you configure the providers once and the system does the rest.
Stack Data Sources
Combine email verification, AI enrichment, and web scraping in a single waterfall pipeline. Chain columns together so scraping feeds into AI analysis in one pass.
Multi-Provider Flexibility
Use different providers for different data types. Optimize your waterfall for each enrichment column based on which provider delivers the best results for your market.

Frequently Asked Questions
What is waterfall enrichment?
Waterfall enrichment is a data enrichment strategy that 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 in the waterfall. This maximizes data coverage and accuracy while minimizing costs by only querying additional providers when needed.
How does waterfall enrichment work in Enrichabl?
Enrichabl implements waterfall enrichment for email verification (through Bounceban and Mailveri) and AI enrichment (through OpenAI and Gemini). For each lead, the system queries the first provider. If the result is missing, uncertain, or low-confidence, it automatically queries the next provider. This ensures maximum coverage without manual intervention.
How is waterfall enrichment different from single-provider enrichment?
Single-provider enrichment queries one data source and accepts whatever it returns - even if the data is incomplete or missing. Waterfall enrichment queries multiple providers in sequence, using fallback logic to fill gaps. This typically increases data coverage by 20-40% compared to relying on a single provider.
Does waterfall enrichment cost more?
Not necessarily. Enrichabl uses a BYOK (Bring Your Own Key) model where you pay data providers directly at their standard rates. The waterfall only queries additional providers when the first one fails to return a result, so you only pay for the lookups you actually need. Combined with Enrichabl's flat $30/month pricing (no per-lead fees), waterfall enrichment is more cost-effective than overpaying for a single premium provider.
Which data providers does Enrichabl support in its waterfall?
Enrichabl currently supports waterfall verification through Bounceban and Mailveri for email validation, and OpenAI and Google Gemini for AI-powered enrichment. Web scraping via Firecrawl adds another data layer. All providers are accessed through your own API keys with no markup.
Can I customize the waterfall order?
Yes. You can configure which providers to use and in what order for each enrichment column. This lets you optimize for cost, accuracy, or speed depending on your use case and the data quality each provider offers for your target market.
