Findymail

Find and verify B2B emails, phones, employees, and company data

Findymail is a B2B contact data platform for finding and verifying work emails, phone numbers, and enriched profile data on company employees. It combines real-time email finding, deliverability verification, reverse-lookup, and technology stack detection in a single API.

With Findymail, you can:

  • Find work emails by name and company: Resolve a verified work email from a person's name plus a company domain or company name.
  • Find emails from LinkedIn: Look up the verified work email behind any LinkedIn profile URL.
  • Find contacts by role: Search a company domain for verified emails matching specific target roles (e.g., CEO, Founder).
  • Verify deliverability: Check whether an email is deliverable and identify the underlying mail provider.
  • Reverse-lookup profiles: Given an email, return the matching LinkedIn URL and an optional enriched profile (job, education, skills, certificates).
  • Enrich companies and employees: Look up company metadata by LinkedIn URL, domain, or name, and find employees by website and target job titles.
  • Find phone numbers: Retrieve a contact's phone number (US-only) from a LinkedIn profile URL.
  • Detect technology stacks: Search the technology catalog or look up the full tech stack of a company by domain.

In Sim, the Findymail integration lets your agents programmatically build verified contact lists, enrich CRMs, qualify leads, and gather technographic data without leaving your workflow. Use it to automate outbound prospecting, augment incoming form submissions, validate email captures before sending, and trigger downstream actions when a verified contact is found.
