Find a verified work email for any professional.

The triangulation pipeline

Contact triangulation runs a prioritized multi-step research pipeline. Each step builds on the previous one, and the process stops as soon as a verified contact is found. The pipeline covers:

1. Profile resolution from existing person records and prior enrichment data
2. LinkedIn profile matching and slug discovery via structured web search
3. Bio link crawling — follows all links in public profile bios, checks each for email addresses, de-obfuscates "name at domain dot com" patterns
4. Professional platform search across Crunchbase, AngelList, About.me, Read.cv, and similar surfaces
5. Document and file search — PDF resumes, conference programs, whitepapers, company directories using file-type search operators
6. Company email pattern detection — finds verified colleague emails on the company domain and derives the likely pattern for the target person
7. WHOIS history lookup when the person is associated with a registered domain
8. Email pattern verification using DNS MX and A record checks before including an address in results

The returned contact includes a confidence score, a source label, and a list of all email addresses found across the pipeline. The primary email is the highest-confidence verified address.

What you provide

Minimum input is a full name and a company name. Additional signals improve accuracy:

• LinkedIn profile URL (if known)
• Company domain
• Post URL or source URL where this person was found (from a scan result, for example)
• Twitter or other social handles
• Bio links from any public profile

The more signals you provide, the faster the pipeline converges and the higher the confidence on the returned email. Without any social links or company domain, the pipeline has to work harder and may return a lower-confidence result or no result.

Credit cost and limits

Contact triangulation costs credits. Your first three enrichments per account are on the house. After that, each enrichment run costs credits against your plan balance. See pricing for current credit costs by plan.

The tool runs in the background while you continue working in MentionFox. You do not need to wait on the page for results. When enrichment completes, the contact record is updated and the email and phone fields become available on the scan card, dealflow entry, and people finder row.

Via API and MCP

Contact triangulation is callable via the MentionFox API and as an MCP tool. The action is triangulate.

Response includes primary_email, confidence, all_emails, phone, and source fields. When a free enrichment credit was used, the response includes free: true.
