TXT is a DNS record, that contains data in human-readable form for external sources to gain information regarding a certain domain or subdomain. In the most common case, this kind of record is employed to prove that you own a domain name in case you're trying to add it to a search engine or to some traffic analytics platform. Since only the domain owner/administrator can add custom DNS records, the TXT record functions as a verification of ownership for the company offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, that helps to ensure that a particular email address isn’t spoofed and that individuals will not get junk mail from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages originate from and serves as confirmation that it's a reliable one. Because there are no standards concerning the content of this type of a record, you can include any other information also.
