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 online search engine or to an analytics platform, that offers information about the traffic to your site. Setting up this kind of a record functions as confirmation that you're the domain owner and they'll supply the content that you should include as the value when you create the record. Another purpose of a TXT record is to verify that an e mail message is sent by the domain address owner and from a reliable server - this is the so-called SPF security, which helps prevent any electronic address created under your domain 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 info which you want to be associated with your domain address in a TXT record as well.
