LeadModule vs FullEnrich: Which Waterfall Enrichment Tool Should You Use?

LeadModule and FullEnrich are both waterfall enrichment tools — they query multiple data providers in sequence and stop when they find a verified email or phone number. The mechanics are similar. The philosophy is not.

FullEnrich is a managed enrichment platform. Point it at a list, it routes through 20+ providers automatically, and returns results. No setup, no provider selection, no BYOK. You pay FullEnrich's credit pricing, and the routing logic is theirs to control.

LeadModule is a configurable waterfall enrichment platform. You choose which providers to use, in what order, and whether to use your own API keys (BYOK) or LeadModule-managed keys. The enrichment runs the way you configure it — not the way the platform decides.

TL;DR:

• FullEnrich fits teams that want enrichment handled with minimal setup and no configuration overhead.
• LeadModule fits teams that want control — BYOK to avoid markups, configurable provider sequences, and API access on all plans.
• If you're already paying for provider subscriptions, LeadModule's BYOK model avoids paying twice.

Side-by-Side Comparison

Pricing and features as of March 2026. See LeadModule pricing and FullEnrich pricing for current rates.

The Core Difference: Managed vs. Configurable

FullEnrich's strength is simplicity. Upload a list, get enriched contacts back. No API key management, no provider research, no sequencing decisions. FullEnrich handles routing across 20+ providers and charges you for results. For teams that want enrichment to just work without ongoing configuration work, that's a real advantage.

The tradeoff: you don't see which providers ran on a given contact, in what order, or why a lookup failed. If find rates drop for a specific audience segment, there's no lever to pull. You can't move a high-performing provider earlier in the sequence or exclude a provider that performs poorly on European contacts.

LeadModule exposes the full configuration layer. You pick providers, set order, and save configs as reusable templates. You can run Prospeo first for a US-focused list, then switch to Dropcontact for European contacts. When you see a drop in match rates, you have something to investigate and adjust.

This matters most at scale. A black-box routing model is fine at low volume. When you're enriching tens of thousands of contacts monthly across multiple client campaigns, the ability to diagnose and optimize the enrichment pipeline has real business impact.

BYOK: Paying Once vs. Paying Twice

If you already pay for provider subscriptions — Prospeo, Findymail, Hunter, Dropcontact — those subscriptions sit unused when you use a managed enrichment platform. FullEnrich routes through providers on your behalf, but you're paying FullEnrich's credit pricing on top of (or instead of) the provider pricing you already pay.

LeadModule's BYOK model routes enrichment through your own API keys. The platform handles orchestration — sequencing, error handling, result normalization — while your provider subscription absorbs the cost. No markup, no double-billing.

BYOK on LeadModule starts at $0 (free tier, with monthly execution limits). The $49/mo Starter plan includes 250 managed credits and expanded BYOK limits for higher volume.

For agencies that have already invested in provider relationships, BYOK is material. At 5,000–10,000 enrichments per month, the cost difference between paying provider rates directly versus paying a managed platform's markup adds up to hundreds of dollars monthly.

Provider Count vs. Provider Coverage

FullEnrich's 20+ provider count is a legitimate selling point. More providers in the waterfall means more shots at finding a contact, especially for edge-case segments: executives at small firms, contacts with outdated job titles, international contacts outside typical US B2B data coverage.

LeadModule's 8 providers are fewer in raw count but cover the main sources most teams rely on: Prospeo, Findymail, LeadMagic, Hunter (sync) and Dropcontact, BetterContact, FullEnrich, and Wiza (async). The configurability argument: for most outbound use cases, 3–4 well-ordered providers cover 90%+ of reachable contacts. Beyond that, provider count runs into diminishing returns — you're hunting progressively harder-to-find contacts with each additional provider.

The practical question is whether you're in the 90% use case (standard B2B outbound, US market, SMB/mid-market contacts) or the 10% case (specialized audiences where extra provider depth earns its keep). Most cold email agencies and RevOps teams are in the first bucket.

API Access and Integrations

Both platforms offer API access. LeadModule's /api/v1/enrich endpoint is available on all plans — pass a name, company, and waterfall config ID, get back a verified result or a structured failure response. The free tier includes API access with execution limits.

LeadModule also ships an MCP server for teams embedding enrichment into AI agent workflows. If you're building enrichment into a GTM automation stack (n8n, Make, custom scripts, or AI-powered prospecting pipelines), API access at the free tier matters.

When to Use FullEnrich

• You want managed enrichment with minimal configuration — no API key management, no provider decisions
• You need access to 20+ provider depth for hard-to-find contact segments
• Your team doesn't have existing provider subscriptions and doesn't want to manage them
• You prefer all-in-one managed pricing without tracking multiple provider accounts

When to Use LeadModule

• You want to configure provider order and optimize enrichment for specific audience segments
• You have existing provider subscriptions and want BYOK to avoid paying a markup
• You need a REST API for enrichment automation and want it on the free tier
• You're an agency managing multiple client campaigns and want reusable waterfall configs
• You want full visibility into which providers run on each enrichment job

The Practical Test

Before choosing either tool, answer one question: do you already pay for any enrichment provider (Prospeo, Findymail, Hunter, Dropcontact, etc.)?

If yes — LeadModule's BYOK model is probably cheaper. You get orchestration without the markup, starting free.

If no — FullEnrich's managed model removes the overhead of setting up and maintaining provider subscriptions. Simpler to start, but you'll pay a bundled rate for every lookup.

For teams that plan to scale outbound beyond a few thousand contacts per month, the cost and control tradeoffs tip toward configurability. Provider subscriptions amortize quickly at volume, and the ability to optimize provider sequences pays off when you're diagnosing fill rate issues across campaign after campaign.
