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