A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or another. The most common use of a TXT record is to add your site to an online search engine or to an analytics platform, that provides info about the traffic to your web site. Creating this sort of a record can serve as proof that you're the domain owner and they will provide the content you need to include as the value when you create the record. Another purpose of a TXT record is to confirm that an email message is sent by the domain address owner and from a reliable server - this is the so-called SPF protection, which helps prevent any electronic address set up under your domain name to be forged and unauthorized people to send junk mail making it appear like it was mailed from your own mailbox. You could add any other information that you would like to be associated with your domain address in a TXT record as well.
