Decoding their Company Email Structure:

Use http://email-format.com/ to decode the structure

If you were looking for an editor at Fast Company who didn't have a publicly listed email address, you could search to decode the structure. For example on this site:

Seeing that the format is [email protected], you can now guess that Erin Schulte's email address is [email protected].

Use this table of the most common formats to make a guess

Check if you're right by putting it in Rapportive

See step 6 ^

If you can't find a format, create a list of permutations:

Make a copy of this spreadsheet and fill in your data

Here's a spreadsheet provided by HubSpot for creating a list of possible email addresses you can check: https://docs.google.com/spreadsheets/d/1s0vi5sbU6zIKZNt1RmTiD4C8AjnP--U2T_EnCjYLeI4/edit#gid=0

Make a copy of this in your own Google Sheets account by going 'File > Make a Copy'.

Replace the generic info with your contact's details and to generate a list of possibilities.

Check the list in MailTester.com

Paste your options into MailTester.com one by one to verify that the email address exists.

This should be a last resort because it's time intensive.
