TXT is a DNS record, containing info in human-readable form for external sources to gain info about a particular domain name or subdomain. In the most common situation, this kind of record is employed to prove that you own a domain name in case you're trying to add it to an Internet search engine or to some traffic analytics platform. Since only the domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the corporation offering the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, which makes sure that a particular email address shall not be spoofed and that others will not get junk e-mail from allegedly your mailbox. The TXT record includes information about the mail server where your digital messages arrive from and functions as confirmation that it is a reliable one. Because there are no standards regarding the content of this kind of a record, you can include any other information also.
