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