A TXT record, as the abbreviation suggests, is a record, that contains information in human-readable form and not code. It may be set up for a domain address or a subdomain for many different purposes. Search engines like Yahoo, for instance, have different ways of verifying that you're the owner of a particular domain and one of them is in fact by creating a TXT record with unique text which they provide and that you must use as the record value. The exact same verification method is employed by some analytics platforms that monitor the traffic to your Internet sites as well. Of course, in such a case the content of the record is going to be read by a robot, but it will still be in human-readable form. A TXT record is also used when you enable the so-called SPF protection for your emails in order to prevent them from being forged. In cases like this, the record contains information showing that a certain electronic message is sent from a dependable and authorized mail server. You could use a TXT record for any sort of other information also, such as your business details, for instance.
