TXT is a DNS record, which contains information in human-readable form for external sources to obtain information about a certain Internet domain or subdomain. In the most common situation, such a record is used to prove that you own a domain name in case you are trying to add it to an Internet search engine or to some site traffic analytics platform. Considering that only the domain name owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the firm supplying the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which helps to ensure that an e-mail address will not be spoofed and that others will not receive junk mail from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages arrive from and functions as verification that it's a trusted one. Because there are no rules regarding the content of this type of a record, you can include any other information also.
