A TXT record, as the abbreviation suggests, is a record, that holds data in human-readable form and not code. It may be created for a domain address or a subdomain for a number of purposes. Search engines like Yahoo, for example, have different ways of making sure you're the owner of a certain domain and one of them is actually by creating a TXT record with unique text that they provide and that you must use as the record value. The same verification method is being employed by some analytics platforms that monitor the traffic to your web sites as well. Of course, in this situation the content of the record will be read by a robot, but it will still be in human-readable form. A TXT record is furthermore used when you enable the so-called SPF protection for your emails in order to protect them from being forged. In this situation, the record contains info showing that a certain digital message is sent from a reliable and authorized mail server. You could use a TXT record for any other information also, like your company details, for instance.
