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