We Tried 6 Keap Enrichment Tools — Here Are the Ones That Delivered in 2026
Keap (formerly Infusionsoft) is built for small business automation, but its data enrichment is limited. We tested six tools and found the ones that actually deliver enriched data into your Keap contacts.
In 2026, Keap is a favorite among small businesses for its CRM, marketing automation, and e-commerce capabilities in one platform. But its contact enrichment is minimal — no auto-populated firmographic data, limited phone number coverage, and basic company information at best.
We tested six enrichment tools that integrate with Keap through native connectors, Zapier, or API — and narrowed it down to the ones that consistently deliver reliable, enriched data without adding complexity to your small business workflow.
TL;DR
- SyncGTM ($99/mo) — Best for waterfall enrichment with Keap sync and workflow automation
- Apollo.io ($49/mo) — Best budget option with 275M+ contacts and Keap-compatible API
- Lusha ($49/mo) — Best for verified direct dials pushed to Keap contacts
- Hunter.io ($49/mo) — Best for email finding and verification with Keap integration
- Snov.io ($39/mo) — Best for email finding + drip campaigns at startup pricing
- FullContact (custom) — Best for identity resolution and customer data enrichment
What We Evaluated
- CRM integration depth — Keap sync via native, Zapier, or API
- Data coverage — email, phone, firmographic accuracy
- Enrichment speed — real-time vs batch processing
- Pricing transparency — total cost for small businesses
- Ease of setup — time from signup to first enriched Keap record
