A TXT record is text in free, human-readable form, that is associated with a domain name as a DNS record for one purpose or other. The most frequent use of a TXT record is to add your site to a search engine or to an analytics platform, that offers info about the web traffic to your site. Setting up such a record serves as proof that you're the Internet domain owner and they will provide the content that you ought to include as the value when you set up the record. Another use of a TXT record is to confirm that an e mail message is sent by the domain address owner and from a trusted hosting server - this is the so-called SPF protection, that prevents any electronic address set up under your domain name to be forged and unauthorized individuals to send out unsolicited mail making it look like it was mailed from your own mailbox. You could include any other info that you would like to be associated with your domain in a TXT record as well.
