Hunter alternative

AgentData vs Hunter: verified emails, plus the company behind them, free

Hunter for verifying and sending; AgentData for finding the companies worth emailing, and their stacks, free.

The verdict

Choose AgentData if you…

• build lists by what companies run, not just who works there
• want emails, people and tech stack in one free lookup instead of one credit per email
• are building an agent and want an MCP server and API without a monthly credit ceiling
• need company profile fields (sector, size, business model, web signals) with the contact
• want to see who just dropped a competitor's tool before you email them

Choose Hunter if you…

• need a dedicated email verifier with a published deliverability track record
• run outreach from the same tool (Hunter Campaigns and sequences are built in)
• rely on Hunter's Chrome extension and Google Sheets add-on in a manual workflow
• want the source URL and date for every address Hunter found

One company, two responses

Hunter's Domain Search returns a list of emails for a domain with a confidence score and verification status; each result costs one credit. AgentData's lookup returns the emails and people alongside the company profile and its technologies for one lookup. Both structures are from the vendors' own documentation, read 17 September 2026.

Why agent builders and growth teams pick AgentData over Hunter

The whole company, not a list of addresses

Hunter tells you who's at a domain. AgentData tells you who's there, what they run, and whether they just changed something.

Profile + technologies + signals + emails + people in one response

Emails with positions; firmographics via a separate Companies call

Browse companies →

No credit per email

A domain with 40 people costs 40 credits on Hunter and one lookup here.

1,000 lookups a day, every returned email included

50 free credits a month; 2,000 for $49

curl -H "Authorization: Bearer $KEY" \
  "https://agentdata.run/api/v1/lookup?domain=intercom.com"

Both have MCP. Ours returns tech stacks and signals your agent can filter on.

Connect in one command and ask for companies by technology, then the people at them.

Hosted MCP + npm, seven tools, no credits

Hunter MCP: Discover, Domain Search, Email Finder, Verifier, enrichment, Leads; credits apply per call

Who moves from Hunter to AgentData

Switching from Hunter

1. Export your leads. Hunter → Leads → Export CSV. Keep Domain (join key), Email, Confidence, Verification status.
2. Re-enrich by domain in AgentData. Loop GET /api/v1/lookup?domain= or upload the domain list; you'll get the company profile and stack plus our verified emails, so you can compare confidence scores side by side.
3. Keep Hunter for what it's best at, if you want. Its verifier and Campaigns don't conflict with using AgentData as the data layer. If you cancel, plans are monthly; annual plans run to term.

Field map: Hunter → AgentData

Where Hunter fits better

• Verification as a product. If you need to verify lists from other sources, Hunter's standalone verifier at 0.5 credit is purpose-built; we only verify what we find.
• Outreach in the same tab. Campaigns, sequences and inbox protection mean Hunter can be the whole stack for a small team.
• Source transparency. Hunter shows the URL where it found each address and when; that audit trail matters for compliance-minded teams.
• Manual, browser-first workflows. The Chrome extension and Google Sheets add-on are mature; we're API and web app.

We would rather you pick the right tool than ours for the wrong reasons. Plenty of teams use Hunter to verify and send and AgentData to decide who to contact.
