TXT is a DNS record, which contains data in human-readable form for external sources to obtain info about a certain domain name or subdomain. In the most common scenario, this sort of record is employed to prove that you own a domain in case you are trying to add it to a search engine or to some web traffic analytics platform. Due to the fact that just the domain owner/administrator is able to add custom DNS records, the TXT record functions as a verification of ownership for the firm supplying the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) protection, which makes sure that a particular email address shall not be spoofed and that others will not get spam from allegedly your mailbox. The TXT record includes details about the mail server where your digital messages originate from and functions as confirmation that it is a trusted one. Since there are no rules about the content of this kind of a record, you can add any other info also.
