TXT is a DNS record, that contains data in human-readable form for external sources to obtain information about a specific domain name or subdomain. In the most common situation, this type of record is employed to prove that you own a domain name in case you are trying to add it to a search engine or to some web traffic analytics platform. As only the Internet domain owner/administrator can add custom DNS records, the TXT record works as a verification of ownership for the company offering the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, that ensures that an e-mail address shall not be spoofed and that others will not get spam from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages arrive from and functions as validation that it is a reliable one. Because there are no standards regarding the content of this sort of a record, you can add any other information as well.
