TXT is a DNS record, that contains information in human-readable form for external sources to get information about a specific Internet domain or subdomain. In the most common case, such a record is used to prove that you own a domain if you're trying to add it to a search engine or to some website traffic analytics platform. Due to the fact that just the domain address owner/administrator is able to add custom DNS records, the TXT record serves as a verification of ownership for the firm providing the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) protection, that helps to ensure that an e-mail address shall not be spoofed and that people will not get spam from allegedly your mailbox. The TXT record contains info about the mail server where your digital messages originate from and serves as validation that it's a reliable one. As there are no rules concerning the content of this sort of a record, you could add any other information also.
