Copy-paste formulas for a Hunter.io alternative in Google Sheets
Paste a formula into row 2, test it on a few rows, then drag down. Outputs are research drafts — always verify contact details before sending.
Company-to-contact research
A: company · B: domain · C: target role
=GPT("For outreach planning, research " & A2 & " (domain " & B2 & "). Target role: " & C2 & ". Return likely department names, common title patterns for this role, and where to verify a real contact. Do not invent specific names or emails.")
Email format guess (verify before use)
A: domain · B: known example email
=GPT("Given domain " & A2 & " and example email format " & B2 & ", describe the likely email pattern (e.g., first.last@). Label it as an unverified guess to confirm with a verification tool before sending.")
Verification / risk flag
A: email · B: source · C: notes
=GPT("Assess this email for outreach risk based only on given context. Email: " & A2 & ". Source: " & B2 & ". Notes: " & C2 & ". Return likely validity signals, risks, and a verify/hold recommendation. Do not claim guaranteed deliverability.")
Outreach note
A: company · B: signal · C: offer
=GPT("Write one outreach note for " & A2 & " from this signal: " & B2 & ". Offer: " & C2 & ". Factual, under 60 words.")
Short answer
A Hunter.io alternative in Google Sheets uses GPT for Sheets to turn a list of companies and domains into contact-research columns: likely departments, title patterns, email-format guesses to verify, and outreach notes — all inside the spreadsheet, without spending per-email credits.
Fastest path: Install GPT for Sheets → add company/domain columns → paste a formula below → review 10 rows → verify before sending.
Important: GPT for Sheets does not scrape private data or guarantee email validity. It produces research drafts and format guesses that you must verify with an appropriate email-verification step before any outreach.
Workflow
What Hunter does and what a Sheets workflow replaces
Hunter is used to find and verify professional emails by domain. A Sheets workflow replaces the research and structuring part: mapping domains to likely departments and title patterns, drafting outreach notes, and flagging which rows need verification. It does not replace a dedicated verification service — keep one in the loop.
| Column | What to put there | Why it matters |
|---|---|---|
| A | Company | Row anchor |
| B | Domain | Grounds research |
| C | Target role | Focuses the search |
| D | Known example email (optional) | Helps infer format |
| E | Contact-research notes | First useful interpretation |
| F | Email-format guess | To verify, never to send blindly |
| G | Verify/hold flag | Controls risk |
| H | Outreach note | Turns research into action |
From company/domain to contact research columns
- Start with 10 representative rows.
- Keep raw fields unchanged in A–D.
- Run research and format-guess formulas, then inspect.
- Always pass email guesses through a verification step.
- Add a verify/hold flag, then fill down.
Accuracy, limits, and verification best practice
AI cannot confirm that a specific email exists or will deliver. Treat any email-format output as an unverified guess, run it through a verification tool, and respect consent and anti-spam rules. Do not use GPT for Sheets to invent personal contact details or to obtain private data — keep research to public, professional context.
Use cases
- Contact research: map domains to likely departments and title patterns.
- Email-format inference: draft a likely pattern to verify, not to send blindly.
- Verification triage: flag which rows need a verification step.
- Personalization: write outreach notes from row signals.
Best for / not best for
Best for: founders, recruiters, and agencies doing outbound who want bulk contact research in Sheets and will verify before sending.
Not best for: teams needing guaranteed email finding/verification at scale — pair with a dedicated verification service for that.

Safety, compliance, and data quality
Treat AI output as a draft. Never present email-format guesses as verified addresses. Verify deliverability with an appropriate tool, do not scrape private data, and follow consent and anti-spam laws. GPT for Sheets is not affiliated with Hunter.io; Hunter is a trademark of its respective owner.
Frequently Asked Questions
Can GPT for Sheets find emails like Hunter.io?
It can research likely email patterns and contact context, but it does not verify that a specific address exists. Treat outputs as unverified guesses and confirm with a verification tool before sending.
Is this scraping?
No. GPT for Sheets works from public, professional context and the data you provide. Do not use it to obtain private personal data.
How do I avoid bad sends?
Verify every email guess with a dedicated verification step, keep a verify/hold flag column, and follow consent and deliverability rules.
Is it affiliated with Hunter.io?
No. GPT for Sheets is independent and not affiliated with or endorsed by Hunter.io.
