Plus addressing
Known officially as subaddressing, plus addressing delivers mail in a particular way so that you can better organize incoming mail. Additionally, plus addressing is used as a method to spot if a company is selling your email address without your permission.
The format for plus addressing is username+word@domain.tld. For example, if my email address is cooper@fbi.gov, a plus addressing version of the address may be cooper+agent@fbi.gov.
Notice the “+” symbol and the word “agent” that follows “cooper”: the email software recognises this format and delivers emails addressed to [cooper+agent@fbi.gov to the “agent” folder.
