TXT is a DNS record, containing info in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common case, this type of record is used to prove that you own a domain if you are trying to add it to an online search engine or to some web traffic analytics platform. As only the domain name owner/administrator can add custom DNS records, the TXT record serves as a proof of ownership for the firm offering the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) protection, which helps to ensure that an e-mail address won't be spoofed and that individuals will not get unsolicited mail from allegedly your mailbox. The TXT record features details about the mail server where your digital messages originate from and serves as proof that it is a reliable one. Since there are no standards about the content of this kind of a record, you can include any other information also.
