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 widespread use of a TXT record is to add your site to an online search engine or to an analytics platform, which provides info about the targeted traffic to your web site. Creating this sort of a record works as confirmation that you are the domain address owner and they'll provide the content that you need to include as the value when you set up the record. Another use of a TXT record is to validate that an email message is sent by the domain name owner and from a reliable hosting server - this is the so-called SPF protection, that prevents any electronic address set up under your domain name to be forged and unauthorized people to send out junk e-mail making it appear like it was sent from your own mailbox. You can include any other information you want to be associated with your domain address in a TXT record as well.
