TXT is a DNS record, containing data in human-readable form for external sources to obtain information about a specific Internet domain or subdomain. In the most common situation, 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 traffic analytics platform. As just the domain address owner/administrator can add custom DNS records, the TXT record works as a verification of ownership for the firm providing the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) protection, which ensures that a particular email address will not be spoofed and that individuals will not receive junk e-mail from allegedly your mailbox. The TXT record includes info about the mail server where your online messages arrive from and serves as confirmation that it's a reliable one. As there are no rules concerning the content of such a record, you can add any other information also.
