TXT is a DNS record, containing information in human-readable form for external sources to obtain information about a certain domain name or subdomain. In the most common case, this sort of record is employed to prove that you own a domain if you're trying to add it to an Internet search engine or to some web traffic analytics platform. Since just the domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the firm providing the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, which makes sure that a particular email address isn’t spoofed and that people will not get junk e-mail from allegedly your mailbox. The TXT record features details about the mail server where your digital messages come from and functions as verification that it is a trusted one. Since there are no standards regarding the content of this kind of a record, you can include any other information as well.
