A TXT record is text in free, human-readable form, which is associated with a domain address as a DNS record for one purpose or other. The most popular use of a TXT record is to add your web site to a search engine or to an analytics platform, which offers information about the web traffic to your site. Setting up this sort of a record functions as verification that you are the domain address owner and they will supply the content you need to include as the value when you set up the record. Another purpose of a TXT record is to verify that an e mail message is sent by the Internet domain owner and from a trusted hosting 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 spam making it look like it was mailed from your own mailbox. You could add any other information that you'd like to be associated with your domain name in a TXT record as well.
