A TXT record is text in free, human-readable form, that's associated with an Internet domain as a DNS record for one purpose or another. The most widespread use of a TXT record is to add your site to a search engine or to an analytics platform, that provides info about the targeted traffic to your website. Setting up this sort of a record can serve as proof that you are the domain owner and they'll provide the content that you ought to include as the value when you set up the record. Another use of a TXT record is to confirm that an e-mail message is sent by the domain owner and from a reliable hosting server - this is the so-called SPF security, which prevents any electronic address set up under your domain name to be forged and unauthorized people to send spam making it appear like it was sent from your own mailbox. You could add any other information that you'd like to be associated with your Internet domain in a TXT record as well.
