TXT is a DNS record, containing information in human-readable form for external sources to gain info about a specific Internet domain or subdomain. In the most common scenario, this sort of record is employed to prove that you own a domain in case you're trying to add it to an online search engine or to some web traffic analytics platform. Considering that only the domain address owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the business supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) protection, that makes sure that an e-mail address isn’t spoofed and that others will not get junk mail from allegedly your mailbox. The TXT record contains details about the mail server where your digital messages originate from and functions as verification that it's a reliable one. As there are no restrictions about the content of such a record, you could add any other info as well.
