A TXT record, as the abbreviation suggests, is a record, that contains data in human-readable form and not code. It could be set up for a domain name or a subdomain for a number of purposes. Search engines, for example, have different ways of making sure you're the owner of a given domain and one of them is by creating a TXT record with unique text which they provide and which you need to use as the record value. The same verification method is being employed by some analytics platforms that check the traffic to your web sites as well. Of course, in this situation the content of the record is going to be read by a robot, but it will still be in human-readable form. A TXT record is furthermore used when you activated the so-called SPF protection for your email addresses so that you can prevent them from being forged. In this case, the record contains data showing that a given electronic message is sent from a trusted and authorized mail server. You can use a TXT record for any other information also, such as your company details, for example.
