How MailFlyr finds and verifies work emails

    Upload your list

    Drop in a CSV of first names, last names and company domains. No special formatting needed.

  2. Step 2

    We find the email

    Our engine works out each person's real work email from just their name and company domain.

  3. Step 3

    We verify it live

    Every address is checked in real time and marked valid, catch-all or invalid, so you know what you're sending to.

  4. Step 4

    Download clean results

Pay only for emails we find

One credit finds one deliverable email, or on paid plans verifies 10 addresses you already have. If we can't find an address, that row costs nothing. The free plan includes 50 credits a month with no card; Starter gives 10,000.

Know when to reach out

Signal monitoring watches your target accounts across 13 public sources: hiring, funding news, SEC and WARN filings, ad activity, tech-stack changes and more. It is included on every plan, Free too.

Use it from your own tools

Paid plans include a developer API for Clay, Zapier, n8n or your own code, plus an MCP server so AI assistants can find and verify emails for you.
