TXT is a DNS record, that contains information in human-readable form for external sources to get information about a specific domain name or subdomain. In the most common case, this kind of record is used to prove that you own a domain name if you are trying to add it to an online search engine or to some traffic analytics platform. Since only the domain name owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the company providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, that helps to ensure that an e-mail address isn’t spoofed and that others will not get junk e-mail from allegedly your mailbox. The TXT record features information about the mail server where your electronic messages originate from and functions as proof that it is a trusted one. Because there are no rules regarding the content of this sort of a record, you could add any other information also.
