A TXT record is text in free, human-readable form, which is associated with a domain address as a DNS record for one purpose or other. The most popular use of a TXT record is to add your web site to a search engine or to an analytics platform, that provides information about the web traffic to your web site. Setting up such a record works as proof that you are the domain name owner and they'll provide the content that you need to include as the value when you create the record. Another use of a TXT record is to verify that an e-mail message is sent by the domain owner and from a trusted web server - this is the so-called SPF protection, which helps prevent any electronic address created under your domain name to be forged and unauthorized people to send junk 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 in a TXT record as well.
