A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or other. The most typical use of a TXT record is to add your website to a search engine or to an analytics platform, that provides info about the targeted traffic to your website. Setting up this kind of a record works as verification that you're the domain address owner and they will provide the content that you need to include as the value when you set up the record. Another purpose of a TXT record is to verify that an e-mail message is sent by the Internet domain owner and from a reliable web server - this is the so-called SPF protection, that prevents any electronic address created under your domain to be forged and unauthorized individuals to send out junk mail making it appear like it was sent from your own mailbox. You can include any other info which you want to be associated with your domain in a TXT record as well.
