A TXT record is text in free, human-readable form, that's associated with a domain address as a DNS record for one purpose or another. The most widespread use of a TXT record is to add your site to an Internet search engine or to an analytics platform, that provides details about the traffic to your website. Setting up this kind of a record may serve as proof that you're the domain owner and they'll supply the content that you should include as the value when you set up the record. Another purpose of a TXT record is to verify that an email message is sent by the domain address owner and from a reliable 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 out unsolicited mail making it look like it was sent from your own mailbox. You could include any other information you want to be associated with your Internet domain in a TXT record as well.
