TXT is a DNS record, which contains information in human-readable form for external sources to obtain info about a specific Internet domain or subdomain. In the most common situation, such a 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. Since only the Internet domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the corporation supplying the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) protection, that ensures that an email address isn’t spoofed and that individuals will not receive spam from allegedly your mailbox. The TXT record includes information about the mail server where your electronic messages originate from and functions as verification that it's a reliable one. Because there are no standards about the content of such a record, you can add any other info as well.
