TXT is a DNS record, that contains information in human-readable form for external sources to obtain information regarding a certain domain name or subdomain. In the most common situation, this kind of record is employed 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. Since only the Internet domain owner/administrator is able to add custom DNS records, the TXT record functions as a proof of ownership for the business providing the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) security, that ensures that an email address won't be spoofed and that individuals will not get unsolicited mail from allegedly your mailbox. The TXT record includes info about the mail server where your digital messages arrive from and serves as confirmation that it's a dependable one. Because there are no restrictions about the content of such a record, you can include any other info as well.
