TXT is a DNS record, which contains information in human-readable form for external sources to get information regarding a specific domain name or subdomain. In the most common scenario, such a record is employed to prove that you own a domain in case you're trying to add it to an Internet search engine or to some web traffic analytics platform. Considering that only the domain name owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the corporation supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, that ensures that an email address won't be spoofed and that individuals will not get spam from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages come from and functions as confirmation that it is a reliable one. Because there are no rules regarding the content of this kind of a record, you could also include any other information as well.
