A TXT record, as the abbreviation suggests, is a record, that keeps data in human-readable form and not code. It can be set up for a domain address or a subdomain for various purposes. Search engines like Google, for instance, have different ways of making sure that you're the owner of a given domain name and one of them is by creating a TXT record with certain text which they provide and that you need to 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. Needless to say, 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 furthermore employed if you enable the so-called SPF protection for your emails in order to protect them from being forged. In cases like this, the record contains information showing that a given electronic message is sent from a reliable and authorized mail server. You could use a TXT record for any kind of other information as well, just like your business details, for instance.
