The other day I was having some fun with mailto. It’s used to produce hyperlinks on websites that allow users to send an email to a specific address without first having to copy it and enter it into an email client. You can use variations of mailto: in Boolean strings to target specific emails. Mailto: is syntax many email systems use (including Outlook) to identify email correspondence. However, many listservs also use the syntax, so it’s a good way to filter results when targeting them.
