A TXT record is text in free, human-readable form, that is associated with a domain name as a DNS record for one purpose or other. The most frequent use of a TXT record is to add your site to a search engine or to an analytics platform, which provides info about the web traffic to your web site. Setting up this kind of a record serves as confirmation that you're the domain owner and they'll provide 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 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 individuals to send out spam making it appear like it was mailed from your own mailbox. You could add any other info you want to be associated with your domain address in a TXT record as well.
