A TXT record is text in free, human-readable form, which is associated with an Internet domain as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your website to an online search engine or to an analytics platform, which offers info about the targeted traffic to your web site. Setting up this type of a record serves as proof that you are the domain owner and they will provide the content you should include as the value when you create the record. Another use of a TXT record is to validate that an email message is sent by the domain address owner and from a reliable web server - this is the so-called SPF protection, which prevents any electronic address created under your domain to be forged and unauthorized individuals to send out unsolicited mail making it appear like it was sent from your own mailbox. You could add any other information you want to be associated with your domain address in a TXT record as well.
