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 an Internet search engine or to an analytics platform, that provides information about the web traffic to your website. Creating such a record serves as confirmation that you're the domain name 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 owner and from a reliable hosting server - this is the so-called SPF protection, which prevents any electronic address created under your domain to be forged and unauthorized individuals to send out spam making it appear like it was sent from your own mailbox. You can include any other info you want to be associated with your domain address in a TXT record as well.
