A TXT record, as the abbreviation implies, is a record, which holds info in human-readable form and not code. It can be set up for a domain or a subdomain for various purposes. Search engines, for example, 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 specific text which they provide and which you must use as the record value. Exactly the same verification method is being employed by some analytics platforms that monitor the traffic to your sites as well. Of course, in this case the content of the record will be read by a robot, but it'll still be in human-readable form. A TXT record is also employed in case you enable the so-called SPF protection for your email addresses in order to shield them from being forged. In cases like this, the record contains data showing that a given electronic message is sent from a reliable and authorized mail server. You can use a TXT record for any sort of other information as well, like your business details, as an example.
