TXT is a DNS record, which contains information in human-readable form for external sources to get info about a certain domain name or subdomain. In the most common situation, this type of record is employed to prove that you own a domain name if you're trying to add it to an Internet search engine or to some site traffic analytics platform. As only the domain owner/administrator is able to add custom DNS records, the TXT record functions as a proof of ownership for the corporation providing the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which ensures that an email address isn’t spoofed and that individuals will not receive junk e-mail from allegedly your mailbox. The TXT record features info about the mail server where your digital messages arrive from and functions as confirmation that it's a trusted one. Because there are no regulations concerning the content of this sort of a record, you can add any other info also.
