TXT is a DNS record, that contains info in human-readable form for external sources to obtain information regarding a specific Internet domain or subdomain. In the most common scenario, this kind of record is used to prove that you own a domain in case you're trying to add it to a search engine or to some site traffic analytics platform. Since just the Internet domain owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the firm providing the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) protection, that ensures that a particular email address won't be spoofed and that individuals will not receive spam from allegedly your mailbox. The TXT record features details about the mail server where your electronic messages originate from and serves as verification that it's a reliable one. Since there are no regulations concerning the content of such a record, you can include any other info as well.
