A TXT record is text in free, human-readable form, which is associated with a domain name 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, which offers information about the web traffic to your web site. Setting up this type of a record can serve as confirmation that you're the domain owner and they'll provide the content that you need to include as the value when you create the record. Another application of a TXT record is to confirm that an e-mail message is sent by the domain address owner and from a reliable web server - this is the so-called SPF protection, that helps prevent any electronic address set up under your domain to be forged and unauthorized people to send junk e-mail making it look like it was sent from your own mailbox. You could add any other info that you would like to be associated with your domain in a TXT record as well.
