8 Close CRM Enrichment Tools Our SDRs Swear By in 2026
Close CRM is built for inside sales teams that need speed. We asked our SDRs to test eight enrichment tools with Close — here are the ones they refuse to give up.
In 2026, Close CRM is purpose-built for inside sales — built-in calling, email, and SMS make it the fastest CRM for SDR workflows. But Close does not include native data enrichment, which means your reps are manually researching prospects or importing incomplete data from external sources.
We gave our SDR team eight enrichment tools that integrate with Close CRM and asked them to use each for a week. Here are the tools they kept using — and the ones they uninstalled on day two.
TL;DR
- SyncGTM ($99/mo) — Best for waterfall enrichment with Close CRM sync and workflow automation
- Apollo.io ($49/mo) — Best budget option combining prospecting, enrichment, and Close sync
- Lusha ($49/mo) — Best for verified direct dials that power Close's built-in dialer
- Hunter.io ($49/mo) — Best for email finding and verification with Close integration
- Snov.io ($39/mo) — Best for email finding + drip campaigns at startup pricing
- Clay ($167/mo) — Best for ops teams building custom enrichment workflows for Close
- RocketReach ($99/mo) — Best for email accuracy at mid-market pricing
- LeadIQ ($45/mo) — Best for SDRs capturing LinkedIn prospects into Close
What We Evaluated
- CRM integration depth — Close CRM sync, custom field mapping, API triggers
- Data coverage — email, phone, firmographic accuracy for inside sales
- Enrichment speed — real-time lookups for SDR workflows
- Pricing transparency — per-record, per-seat, or flat-rate
- SDR workflow fit — does the tool speed up or slow down prospecting?
