TXT is a DNS record, which contains info in human-readable form for external sources to gain information about a specific Internet domain or subdomain. In the most common case, this type of record is used to prove that you own a domain if you're trying to add it to a search engine or to some site traffic analytics platform. Since only the domain address owner/administrator is able to add custom DNS records, the TXT record serves as a verification of ownership for the firm offering the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) protection, that ensures that a particular email address will not be spoofed and that others will not receive spam from allegedly your mailbox. The TXT record features information about the mail server where your electronic messages originate from and serves as proof that it's a trusted one. Because there are no restrictions regarding the content of this kind of a record, you could add any other information as well.
