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 widespread use of a TXT record is to add your web site to an Internet search engine or to an analytics platform, which offers details about the traffic to your web site. Creating this sort of a record may serve as verification that you are the domain name owner and they will supply the content you should include as the value when you set up the record. Another purpose of a TXT record is to confirm that an e-mail message is sent by the domain address owner and from a reliable 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 people to send junk e-mail making it look like it was mailed from your own mailbox. You could add any other info you want to be associated with your domain name in a TXT record as well.
