TXT is a DNS record, which contains info in human-readable form for external sources to obtain information regarding a particular Internet domain or subdomain. In the most common case, this sort 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. Due to the fact that only the domain owner/administrator can add custom DNS records, the TXT record functions as a verification of ownership for the corporation supplying the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) security, which ensures that an e-mail address will not be spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record contains details about the mail server where your electronic messages come from and functions as proof that it's a trusted one. Because there are no regulations concerning the content of this kind of a record, you could also include any other info also.
