TXT is a DNS record, containing info in human-readable form for external sources to gain information about a particular domain or subdomain. In the most common case, such a record is employed 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. Considering that only the domain owner/administrator can add custom DNS records, the TXT record functions as a verification of ownership for the corporation offering 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 individuals will not receive unsolicited mail from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages originate from and functions as validation that it's a trusted one. Since there are no regulations regarding the content of such a record, you can include any other information also.
