A TXT record is text in free, human-readable form, that 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 web site to an Internet search engine or to an analytics platform, that offers information about the web traffic to your web site. Creating such a record may serve as confirmation that you are the domain address owner and they'll supply the content you need to include as the value when you create the record. Another purpose of a TXT record is to validate that an e-mail message is sent by the domain address owner and from a reliable hosting server - this is the so-called SPF security, that helps prevent any electronic address set up under your domain name to be forged and unauthorized individuals to send out junk e-mail making it look like it was mailed from your own mailbox. You could include any other info you want to be associated with your Internet domain in a TXT record as well.
