A TXT record is text in free, human-readable form, that's associated with a domain name as a DNS record for one purpose or another. The most popular use of a TXT record is to add your web site to an online search engine or to an analytics platform, that provides information about the traffic to your site. Setting up this type of a record works as verification that you are the domain address owner and they will supply the content you need to include as the value when you set up the record. Another use of a TXT record is to verify that an email message is sent by the domain name owner and from a reliable hosting server - this is the so-called SPF security, which helps prevent any electronic address created under your domain name to be forged and unauthorized individuals to send out junk mail making it look like it was sent from your own mailbox. You could add any other info that you'd like to be associated with your Internet domain in a TXT record as well.
