Free tool
Check an email for free
Paste a work address. We check format, mail servers, throwaway domains, and mailbox signals — then you can take the company into Lead Search if it is worth pursuing.
Same signals as our email verification API. Limited per network. For bulk checks in Lead Search, create a free account.
Frequently asked questions
- Is this email checker free?
- Yes. You can check a work email without creating an account. We limit checks per network so the tool stays available. Sign up to verify more addresses inside Lead Search.
- What does the free check tell me?
- Whether the address is well-formed, whether the domain has a mail server, whether it looks disposable or like a role inbox (info@, sales@), and a deliverability signal when we can reach the checker service.
- Do you store the emails I check?
- The public checker does not save addresses to a CRM or marketing list. Rate limits use your network address only. For pipeline work, create an account and verify people on companies you already researched.
