TXT is a DNS record, containing information in human-readable form for external sources to get info about a specific domain or subdomain. In the most common case, this kind of record is employed to prove that you own a domain if you are trying to add it to an online search engine or to some traffic analytics platform. As only the Internet domain owner/administrator is able to add custom DNS records, the TXT record works as a proof of ownership for the company supplying the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, which makes sure that an email address won't be spoofed and that individuals will not get spam from allegedly your mailbox. The TXT record includes information about the mail server where your digital messages originate from and serves as validation that it is a reliable one. Since there are no rules concerning the content of such a record, you can include any other information also.
