A TXT record, as the abbreviation implies, is a record, which contains info in human-readable form and not code. It could be set up for a domain or a subdomain for many different purposes. Search engines like Yahoo, for instance, have different ways of confirming you're the owner of a particular domain and one of them is actually by creating a TXT record with specific text which they provide and that you will 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 web 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 additionally employed when you activated the so-called SPF protection for your e-mails so that you can shield them from being forged. In this situation, the record contains information showing that a certain electronic message is sent from a trusted and authorized mail server. You could use a TXT record for any sort of other information as well, such as your company details, for instance.
