TXT is a DNS record, that contains info in human-readable form for external sources to gain info about a particular domain or subdomain. In the most common scenario, this kind of record is employed to prove that you own a domain in case you are trying to add it to an Internet search engine or to some site traffic analytics platform. As just the domain address owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the company providing the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which helps to ensure that a particular email address shall not be spoofed and that others will not receive spam from allegedly your mailbox. The TXT record includes details about the mail server where your digital messages arrive from and serves as validation that it's a trusted one. Since there are no rules regarding the content of this type of a record, you could add any other information also.
