A TXT record is text in free, human-readable form, which is 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 website to a search engine or to an analytics platform, which provides details about the traffic to your website. Setting up this type of a record works as verification that you are the domain name owner and they'll provide the content you should 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 trusted server - this is the so-called SPF security, that prevents any electronic address set up under your domain to be forged and unauthorized people to send out unsolicited mail making it look like it was mailed from your own mailbox. You may include any other info that you'd like to be associated with your domain in a TXT record as well.
