A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or another. The most widespread use of a TXT record is to add your web site to an online search engine or to an analytics platform, that provides details about the targeted traffic to your website. Setting up this type of a record functions as confirmation that you're the domain name owner and they will provide the content that you ought 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 server - this is the so-called SPF security, which helps prevent any electronic address set up under your domain to be forged and unauthorized people to send junk mail making it look like it was mailed from your own mailbox. You could add any other information you want to be associated with your domain in a TXT record as well.
