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 typical use of a TXT record is to add your web site to a search engine or to an analytics platform, that offers details about the web traffic to your Internet site. Creating such a record serves as verification that you are the domain owner and they will supply the content you should include as the value when you create the record. Another use of a TXT record is to validate that an email message is sent by the domain address owner and from a trusted server - this is the so-called SPF security, that helps prevent any electronic address created under your domain name to be forged and unauthorized individuals to send out junk mail making it appear like it was mailed from your own mailbox. You could include any other info that you'd like to be associated with your domain address in a TXT record as well.
