TXT is a DNS record, which contains info in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common situation, such a 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. As only the domain owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the company offering the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) protection, which helps to ensure that an e-mail address isn’t spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record features information about the mail server where your online messages arrive from and serves as proof that it's a dependable one. Because there are no rules concerning the content of such a record, you can include any other info also.
