TXT is a DNS record, which contains info in human-readable form for external sources to get information about a specific domain name or subdomain. In the most common situation, such a record is employed to prove that you own a domain if you are trying to add it to a search engine or to some site traffic analytics platform. Considering that only the domain address owner/administrator is able to add custom DNS records, the TXT record serves as a verification of ownership for the business supplying the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) protection, which makes sure that an e-mail address will not be spoofed and that individuals will not get unsolicited mail from allegedly your mailbox. The TXT record contains details about the mail server where your electronic messages originate from and functions as proof that it is a trusted one. Because there are no regulations regarding the content of such a record, you could add any other information as well.
