I Tested 8 Streak CRM Enrichment Tools — These Work Right From Gmail in 2026
Streak CRM lives inside Gmail, so your enrichment tools need to work there too. I tested eight tools and found which ones seamlessly enrich contacts without leaving your inbox.
In 2026, Streak CRM turns Gmail into a CRM — pipelines, contact management, and deal tracking all inside your inbox. But Streak does not include native data enrichment, which means your pipeline contacts often have just a name and email address with no company data, phone numbers, or firmographic details.
I tested eight enrichment tools that work alongside Streak's Gmail-native interface. The best ones enrich contacts right from your browser — using Chrome extensions, Zapier, or API connections — without disrupting the Gmail workflow that makes Streak so productive.
TL;DR
- SyncGTM ($99/mo) — Best for waterfall enrichment with Streak-compatible API and workflow automation
- Apollo.io ($49/mo) — Best budget option with Chrome extension that works alongside Streak in Gmail
- Lusha ($49/mo) — Best for verified direct dials from the Chrome sidebar next to Streak
- Hunter.io ($49/mo) — Best for email finding and verification in a Gmail-native workflow
- Snov.io ($39/mo) — Best for email finding + drip campaigns at startup pricing
- Clay ($167/mo) — Best for ops teams building custom enrichment workflows
- RocketReach ($99/mo) — Best for email accuracy at mid-market pricing
- FullContact (custom) — Best for identity resolution across Gmail contacts
What We Evaluated
- Gmail compatibility — Chrome extension and inbox-native experience
- CRM integration depth — Streak sync via API or Zapier
- Data coverage — email, phone, firmographic accuracy
- Pricing transparency — total cost for small teams
- Workflow friction — does it slow down or speed up the Gmail experience?
