A TXT record is text in free, human-readable form, that is associated with a domain address as a DNS record for one purpose or another. The most common use of a TXT record is to add your web site to a search engine or to an analytics platform, that offers info about the web traffic to your web site. Creating such a record may serve as confirmation that you're the Internet domain owner and they'll supply the content you should include as the value when you set up the record. Another purpose of a TXT record is to verify that an email message is sent by the Internet domain owner and from a reliable web server - this is the so-called SPF protection, which prevents any electronic address set up under your domain name to be forged and unauthorized people to send spam making it look like it was mailed from your own mailbox. You could add any other information that you would like to be associated with your domain in a TXT record as well.
