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 other. The most popular use of a TXT record is to add your site to an online search engine or to an analytics platform, that offers details about the targeted traffic to your site. Creating this kind of a record serves as verification that you are the Internet domain owner and they'll supply the content that you should include as the value when you set up the record. Another application of a TXT record is to validate that an e-mail message is sent by the domain address owner and from a trusted hosting server - this is the so-called SPF security, that helps prevent any electronic address set up under your domain to be forged and unauthorized individuals to send out junk e-mail making it look like it was sent from your own mailbox. You could include any other info that you would like to be associated with your domain address in a TXT record as well.
