TXT is a DNS record, containing information in human-readable form for external sources to get information regarding a specific Internet domain or subdomain. In the most common situation, such a record is used to prove that you own a domain name in case you're trying to add it to an Internet search engine or to some traffic analytics platform. Due to the fact that only the domain address owner/administrator can add custom DNS records, the TXT record works as a proof of ownership for the business supplying the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) protection, that helps to ensure that a particular email address will not be spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record contains details about the mail server where your digital messages originate from and functions as confirmation that it's a reliable one. Because there are no standards about the content of such a record, you could also include any other information as well.
