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 another. The most common use of a TXT record is to add your web site to a search engine or to an analytics platform, that provides info about the targeted traffic to your site. Setting up this sort of a record can serve as proof that you're the domain address owner and they will supply the content you should include as the value when you set up the record. Another use of a TXT record is to validate that an e mail message is sent by the Internet domain owner and from a trusted web server - this is the so-called SPF security, that prevents any electronic address created under your domain to be forged and unauthorized people to send out junk mail making it look like it was mailed from your own mailbox. You can include any other information that you would like to be associated with your domain in a TXT record as well.
