A TXT record is text in free, human-readable form, that is associated with a domain address as a DNS record for one purpose or other. The most typical use of a TXT record is to add your site to a search engine or to an analytics platform, that offers info about the targeted traffic to your website. Setting up this sort of a record may serve as confirmation that you are the domain owner and they'll provide the content that you need to include as the value when you create the record. Another purpose of a TXT record is to validate that an e-mail message is sent by the domain owner and from a reliable 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 junk mail making it look like it was mailed from your own mailbox. You may include any other information that you would like to be associated with your domain in a TXT record as well.
