Frequently asked questions
What is an email permutator?
A tool that writes a person's name every way a work address can be built (jane.doe@, jane@, jdoe@ and so on) at their company's domain, so you can check the likely ones instead of guessing. This one ranks them by how startups actually write their addresses, from ones we've verified.
What is the most common email format?
At startups it's first name, a dot, then last name ([email protected]): 44% of the 706 startups whose addresses we've verified write them that way. Next come first name only ([email protected]) at 31% and first initial followed by last name ([email protected]) at 20%. Those three cover 95%.
How do I find someone's work email?
Get their name and their company's domain: the job posting, the team page or LinkedIn usually has both. Put them in the permutator, start with the company's own format when we know it, else the most common one, and check the address with an email verifier before you send.
Should I email every address on the list?
No. Each one that doesn't exist bounces, and bounces count against you: send enough of them and your emails start landing in spam. Check the top one or two with an email verifier, which asks the company's mail server whether the mailbox exists without sending anything, and send to the one it confirms.
Why does a verifier say "accept all"?
Some companies' mail servers say yes to every address, real or not, so a verifier can't tell which one is right. Send to the company's own format, or the most common one, and watch for a bounce.
Does this tool store what I type?
No. The addresses are worked out in your browser, and we don't send or keep the names or domains you type.
