A TXT record is text in free, human-readable form, which is associated with a domain as a DNS record for one purpose or other. The most widespread use of a TXT record is to add your site to a search engine or to an analytics platform, which offers details about the web traffic to your Internet site. Setting up this sort of a record can serve as confirmation that you're the Internet domain owner and they will provide the content you should include as the value when you set up the record. Another purpose of a TXT record is to verify that an e-mail message is sent by the domain owner and from a trusted server - this is the so-called SPF security, which prevents any electronic address created under your domain to be forged and unauthorized people to send out junk mail making it appear like it was mailed from your own mailbox. You could add any other information which you want to be associated with your domain in a TXT record as well.
