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 other. The most typical use of a TXT record is to add your website to an online search engine or to an analytics platform, that offers details about the web traffic to your site. Setting up such a record can serve as proof that you're the domain address owner and they will provide the content you need to include as the value when you set up the record. Another use of a TXT record is to validate that an email message is sent by the domain address 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 spam making it appear like it was sent from your own mailbox. You could include any other information that you would like to be associated with your domain address in a TXT record as well.
