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, that provides info about the web traffic to your site. Setting up this type of a record may serve as proof that you're the Internet 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 validate that an email message is sent by the domain address owner and from a reliable server - this is the so-called SPF protection, which prevents any electronic address created under your domain name to be forged and unauthorized individuals to send out junk mail making it appear like it was sent from your own mailbox. You could include any other info which you want to be associated with your Internet domain in a TXT record as well.
