TXT is a DNS record, which contains info in human-readable form for external sources to get information about a specific Internet domain or subdomain. In the most common situation, this type of record is used to prove that you own a domain name in case you're trying to add it to an online search engine or to some site traffic analytics platform. Since just the domain owner/administrator may add custom DNS records, the TXT record works as a proof of ownership for the corporation providing the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) protection, that makes sure that a particular email address isn’t spoofed and that individuals will not get spam from allegedly your mailbox. The TXT record includes information about the mail server where your digital messages originate from and functions as validation that it's a reliable one. Because there are no rules regarding the content of such a record, you can add any other info as well.
