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 typical use of a TXT record is to add your site to a search engine or to an analytics platform, that provides information about the traffic to your Internet site. Creating such a record functions as proof that you're the domain owner and they will provide the content that you should include as the value when you set up the record. Another use of a TXT record is to verify that an e-mail message is sent by the Internet domain owner and from a trusted server - this is the so-called SPF protection, that prevents any electronic address set up under your domain name to be forged and unauthorized individuals to send out junk mail making it appear like it was mailed from your own mailbox. You could add any other information you want to be associated with your domain address in a TXT record as well.
