Reaching the right person usually starts with the right email address. These free tools work out the addresses a person could have at a company, pull every address out of the files you already have, and suggest addresses to create when you set up a new mailbox.

The email permutator lists every common format for a name and domain, from first.last@ to initials, starting with the ones companies use most. If you already know one address at the company, the pattern finder works out the exact format it uses and applies it to anyone else. The email extractor reads PDFs, Word, Excel, CSV, email files and ZIPs, and lists every address inside, and the duplicate email finder spots addresses that repeat in a list or across files and gives the list back with each one once. When you have the address, the cold email templates cover what to send, from the first email to the follow-ups and the breakup. Before you send, the email checker cleans your list, the subject line tester and spam checker review your copy, the warmup calculator plans how fast a new mailbox can ramp, and the signature generator finishes every email. Smaller utilities cover the rest: Gmail aliases, Outlook address ideas, mailto links, plain-text versions of HTML emails, and attachment size limits. The email generator suggests professional, casual and creative addresses for yourself, a new hire or a personal brand. All of them run in your browser, so nothing you type or upload is sent anywhere.
