A TXT record is text in free, human-readable form, which is associated with a domain name as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your site to a search engine or to an analytics platform, that provides info about the web traffic to your site. Setting up this type of a record works as verification that you're the domain owner and they'll supply the content that 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 reliable hosting server - this is the so-called SPF protection, which helps prevent any electronic address set up under your domain to be forged and unauthorized people to send spam making it appear like it was sent from your own mailbox. You can include any other information that you would like to be associated with your domain address in a TXT record as well.
