A TXT record, as the abbreviation suggests, is a record, which keeps data in human-readable form and not code. It may be created for a domain name or a subdomain for various purposes. Search engines, for example, have different ways of confirming that you're the owner of a given domain name and one of them is actually by creating a TXT record with certain text that they provide and that you must use as the record value. The exact same verification method is used by some analytics platforms that keep track of the traffic to your sites as well. However, 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 activated the so-called SPF protection for your emails so that you can protect them from being forged. In cases like this, the record contains info showing that a particular electronic message is sent from a reliable and authorized mail server. You could use a TXT record for any type of other information as well, just like your company details, for instance.
