TXT is a DNS record, that contains data in human-readable form for external sources to obtain info about a specific domain or subdomain. In the most common scenario, this sort of record is used to prove that you own a domain in case you're trying to add it to a search engine or to some website traffic analytics platform. Since just the Internet domain owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the firm offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, that ensures that an email address shall not be spoofed and that individuals will not get spam from allegedly your mailbox. The TXT record features info about the mail server where your digital messages come from and functions as proof that it is a trusted one. Because there are no regulations concerning the content of this kind of a record, you can include any other information as well.
