TXT is a DNS record, which contains info in human-readable form for external sources to get information regarding a certain Internet domain or subdomain. In the most common scenario, this type of record is employed to prove that you own a domain name if you're trying to add it to an online search engine or to some traffic analytics platform. Since just the domain name owner/administrator is able to add custom DNS records, the TXT record works as a proof of ownership for the corporation offering the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) protection, that ensures that an e-mail address shall not be spoofed and that people will not receive junk mail from allegedly your mailbox. The TXT record contains information about the mail server where your electronic messages come from and functions as proof that it is a trusted one. Because there are no rules about the content of this kind of a record, you can include any other info also.
