TXT is a DNS record, containing information in human-readable form for external sources to gain information about a particular domain name or subdomain. In the most common situation, this type of record is employed to prove that you own a domain name in case you're trying to add it to a search engine or to some web traffic analytics platform. Since only the domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the firm offering the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) protection, that helps to ensure that a particular email address won't be spoofed and that individuals will not get unsolicited mail from allegedly your mailbox. The TXT record contains info about the mail server where your electronic messages originate from and serves as validation that it's a trusted one. As there are no regulations regarding the content of this sort of a record, you can add any other info also.
