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 widespread use of a TXT record is to add your site to an online search engine or to an analytics platform, that provides details about the traffic to your web site. Setting up such a record serves as verification that you are the Internet domain owner and they'll supply the content that you should include as the value when you set up the record. Another use of a TXT record is to verify that an e mail message is sent by the domain name owner and from a reliable hosting server - this is the so-called SPF security, which prevents any electronic address set up under your domain to be forged and unauthorized people to send out spam making it appear like it was sent from your own mailbox. You may include any other information you want to be associated with your domain name in a TXT record as well.
