A TXT record is text in free, human-readable form, that is associated with an Internet domain as a DNS record for one purpose or other. The most common use of a TXT record is to add your web site to an Internet search engine or to an analytics platform, that provides information about the targeted traffic to your Internet site. Setting up this sort of a record serves as verification that you are the Internet domain owner and they'll provide the content you should include as the value when you set up the record. Another application of a TXT record is to verify that an email message is sent by the Internet domain owner and from a trusted web 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 junk e-mail making it appear like it was sent from your own mailbox. You could add any other info which you want to be associated with your domain address in a TXT record as well.
