Free email finder, verifier, and DNS tools
Free work email finder and verifier, plus MX lookup, SPF/DKIM/DMARC checker, permutator, generators, and calculators. DNS tools are uncapped.
Each tool is a working page, not a signup wall. DNS lookups, generators, the permutator, and the calculators are free and uncapped. Finder, verifier, and catch-all share a small daily cap with the homepage because they talk to live mail servers — then it is the same product you would use in the dashboard.
Open any tool for the full guide: what it checks, how to read the result, when it is the wrong instrument, and the mistakes that bounce a sending domain. Illustrative addresses on those pages are always jane.doe@company.com-style fiction, never a real person.
Free work email finder (name + domain)
Find a work email from a name and company domain. Checked against the mail server, not guessed from a database.
Free email verifier: check if a mailbox exists
Check whether a work mailbox exists without sending mail to it. Catch-alls are labelled, not dressed up as verified.
Free email permutator: every email format for a name
Generate every common work-email pattern for a name and domain. Candidates only — we never publish a real person's address.
MX lookup: check a domain's mail server
See which mail server a domain uses, and whether it looks like Google Workspace, Microsoft 365, or something else.
SPF, DKIM and DMARC checker (free)
Look up the three DNS records that decide whether Gmail and Outlook trust mail from a domain.
Free SPF record generator
Build a v=spf1 TXT record from the providers you actually send through.
Free DMARC record generator
Build a _dmarc TXT record. Start at p=none, then tighten once the reports look clean.
Catch-all email checker: is the domain accept-all?
Some domains accept mail to any address. No verifier can confirm a mailbox there — we detect it and tell you.
Email bounce rate calculator
See what a bounce rate does to a sending domain, not just to one campaign.
Cold email ROI calculator
What a list of verified work emails costs at each vendor's own published rate, including ours.
