TXT is a DNS record, containing data in human-readable form for external sources to gain info about a specific Internet domain or subdomain. In the most common case, this sort of record is employed to prove that you own a domain in case you're trying to add it to an online search engine or to some site traffic analytics platform. As only the domain owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the business providing the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) security, which helps to ensure that an e-mail address won't be spoofed and that people will not get unsolicited mail from allegedly your mailbox. The TXT record features information about the mail server where your digital messages come from and serves as proof that it's a trusted one. Because there are no regulations regarding the content of such a record, you can add any other info also.
