You have a name and a company, but no email. Rather than guess one pattern and hope it lands, this gives you every realistic pattern at once so a validator can do the confirming. Type a first name, a last name, and a domain — the corporate one (the part after the @) or one of the common personal domains you can tick (gmail, outlook, icloud, proton, and a few more).
Feed it André Dupont at acme.com and you get the full 24-pattern matrix — [email protected], [email protected], [email protected], [email protected], and the rest. Accents are normalised, so André and Andre produce the same list; you don’t have to think about diacritics. Click any cell to copy it, or hit “Copy all” to grab the whole set. Tick more than one domain and it runs the same name across each, grouped by domain.
A worked example beats a wall of text: tick both acme.com and gmail.com for the same person and you cover the official inbox and the one a founder or freelancer actually reads.
One honest limit: this only builds the candidates — it does not verify them. None of these addresses are confirmed real until you run them through Hunter, NeverBounce, or any SMTP check. The Permutator narrows the field; validation tells you which one delivers.
