TXT is a DNS record, containing data in human-readable form for external sources to gain information regarding a particular domain or subdomain. In the most common case, such a record is employed to prove that you own a domain name if you are trying to add it to an Internet search engine or to some web traffic analytics platform. Considering that only the domain owner/administrator is able to add custom DNS records, the TXT record functions as a proof of ownership for the company providing the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which helps to ensure that an e-mail address won't be spoofed and that individuals will not receive junk e-mail from allegedly your mailbox. The TXT record includes information about the mail server where your digital messages arrive from and functions as proof that it's a reliable one. Because there are no rules regarding the content of this type of a record, you can include any other info also.
