TXT is a DNS record, which contains data in human-readable form for external sources to gain information regarding a specific Internet domain or subdomain. In the most common case, this kind of record is employed to prove that you own a domain name if you're trying to add it to an online search engine or to some site traffic analytics platform. Since just the Internet domain owner/administrator is able to add custom DNS records, the TXT record works as a verification of ownership for the company offering the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, that makes sure that an e-mail address isn’t spoofed and that people will not receive unsolicited mail from allegedly your mailbox. The TXT record features information about the mail server where your online messages originate from and functions as proof that it's a dependable one. Since there are no standards concerning the content of this kind of a record, you can include any other information also.
