A TXT record is text in free, human-readable form, that is associated with a domain as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your web site to an online search engine or to an analytics platform, that offers information about the traffic to your site. Setting up this type of a record functions as confirmation that you are the domain owner and they will supply the content that you should include as the value when you set up the record. Another use of a TXT record is to validate that an e-mail message is sent by the Internet domain owner and from a trusted web server - this is the so-called SPF protection, which helps prevent any electronic address set up under your domain name to be forged and unauthorized people to send out unsolicited mail making it appear like it was mailed from your own mailbox. You could add any other information which you want to be associated with your domain name in a TXT record as well.
