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 site to an online search engine or to an analytics platform, which provides information about the web traffic to your site. Setting up such a record can serve as proof that you are the domain address owner and they'll supply the content that you ought to include as the value when you create the record. Another use of a TXT record is to validate that an email message is sent by the domain address owner and from a trusted server - this is the so-called SPF security, which helps prevent 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 can include any other info which you want to be associated with your domain address in a TXT record as well.
