TXT is a DNS record, containing information in human-readable form for external sources to gain information about a certain domain name or subdomain. In the most common case, this type of record is used to prove that you own a domain name if you're trying to add it to an online search engine or to some web traffic analytics platform. Since just the domain name owner/administrator may add custom DNS records, the TXT record works as a proof of ownership for the business supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, that ensures that a particular email address will not be spoofed and that people will not get junk mail from allegedly your mailbox. The TXT record includes information about the mail server where your digital messages arrive from and serves as proof that it's a reliable one. As there are no restrictions about the content of this type of a record, you can add any other information as well.
