A TXT record is text in free, human-readable form, that is associated with a domain as a DNS record for one purpose or other. The most typical use of a TXT record is to add your site to an online search engine or to an analytics platform, which offers information about the targeted traffic to your site. Setting up this sort of a record functions as verification that you're the domain owner and they will supply the content that you should include as the value when you set up the record. Another application of a TXT record is to confirm that an email message is sent by the domain address owner and from a trusted web server - this is the so-called SPF protection, that prevents any electronic address set up under your domain to be forged and unauthorized people to send unsolicited mail making it appear like it was mailed from your own mailbox. You can include any other information that you'd like to be associated with your domain name in a TXT record as well.
