TXT is a DNS record, that contains info in human-readable form for external sources to gain info about a certain Internet domain or subdomain. In the most common situation, this sort of record is used to prove that you own a domain name if you're trying to add it to an Internet search engine or to some web traffic analytics platform. Considering that only the Internet domain owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the corporation providing the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, that ensures that an e-mail address shall not be spoofed and that individuals will not receive junk mail from allegedly your mailbox. The TXT record includes details about the mail server where your electronic messages originate from and functions as confirmation that it's a reliable one. Since there are no standards about the content of this sort of a record, you can add any other info also.
