TXT is a DNS record, containing info in human-readable form for external sources to get info about a specific domain or subdomain. In the most common case, such a record is employed to prove that you own a domain if you are trying to add it to an Internet search engine or to some site traffic analytics platform. Considering that only the domain owner/administrator is able to add custom DNS records, the TXT record works as a verification of ownership for the business providing the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, which ensures that a particular email address will not be spoofed and that others will not receive junk e-mail 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 dependable one. As there are no restrictions about the content of this kind of a record, you could add any other information also.
