About
What is SellHack
SellHack finds and verifies email addresses and phone numbers, then lets you build and export prospect lists directly from a Chrome extension as you browse. It's built for SDRs, BDRs, and founders at solo or small-team stages who need contact data without paying enterprise prices. The standout capability is its ability to create custom audiences from your prospect lists for retargeting on platforms like Facebook and Google — a step beyond what most email finders offer. Cold email automation and integrations with Salesforce and Replyify round out the workflow. Where it falls short: the credit-based model means volume prospectors will hit limits quickly, and the data depth doesn't match larger enrichment platforms at scale.

Our verdict
Vanderbuild take
SellHack is a no-frills email finder and verifier that makes sense for SDRs and founders who need verified contact data at a low entry cost — it doesn't try to be a full sales platform, and that focus is its strength. On the agentic side, the REST API is real and documented, so you can wrap SellHack into your own MCP layer or automation stack without much friction — it's Capable, not native, but workable. At $3/mo to start with a free credit allotment, the risk to test is essentially zero. The honest limitation is scale: credit caps mean this gets expensive or slow for anyone running high-volume prospecting, and the integration list is thin enough that you'll likely need middleware to connect it to anything beyond Salesforce or Replyify.
