A TXT record, as the abbreviation indicates, is a record, that keeps information in human-readable form and not code. It may be created for a domain address or a subdomain for many different purposes. Search engines like Yahoo, for instance, have different ways of making sure you're the owner of a given domain name and one of them is actually by creating a TXT record with unique text which they provide and which you must use as the record value. The same verification method is employed by some analytics platforms that monitor the traffic to your websites as well. However, 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 also used when you activated the so-called SPF protection for your e-mails in order to prevent them from being forged. In this case, the record contains information showing that a certain electronic message is sent from a reliable and authorized mail server. You may use a TXT record for any kind of other information as well, like your business details, for instance.
