A TXT record is text in free, human-readable form, that is associated with an Internet domain as a DNS record for one purpose or another. The most popular use of a TXT record is to add your website to an Internet search engine or to an analytics platform, which offers information about the traffic to your site. Setting up this kind of a record can serve as verification that you're the domain name owner and they'll supply the content that you need to include as the value when you create the record. Another purpose of a TXT record is to validate that an e-mail message is sent by the domain address owner and from a reliable web server - this is the so-called SPF protection, that prevents any electronic address created under your domain name to be forged and unauthorized individuals to send spam making it appear like it was sent from your own mailbox. You could include any other information which you want to be associated with your domain address in a TXT record as well.
