In the most common scenario, this kind of record is employed to prove that you own a domain in case you're trying to add it to an online search engine or to some website traffic analytics platform. Due to the fact that only the domain owner/administrator is able to add custom DNS records, the TXT record works as a verification of ownership for the corporation supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, that helps to ensure that an email address shall not be spoofed and that individuals will not get junk e-mail from allegedly your mailbox.

Since there are no standards concerning the content of this type of a record, you could add any other info also.
