A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your web site to an online search engine or to an analytics platform, which provides details about the web traffic to your web site. Setting up this sort of a record works as verification that you are the domain name owner and they'll provide the content that you should include as the value when you create the record. Another use 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 helps prevent any electronic address created under your domain to be forged and unauthorized individuals to send out unsolicited mail making it appear like it was mailed from your own mailbox. You could add any other information you want to be associated with your domain in a TXT record as well.
