TXT is a DNS record, which contains data in human-readable form for external sources to obtain information about a certain domain name or subdomain. In the most common situation, such a record is used to prove that you own a domain in case you are trying to add it to an Internet search engine or to some site traffic analytics platform. As only the domain address 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 sort of records is the email SPF (Sender Policy Framework) protection, that makes sure that an email address will not be spoofed and that people will not receive junk e-mail from allegedly your mailbox. The TXT record features details about the mail server where your online messages arrive from and functions as verification that it is a dependable one. As there are no standards about the content of this sort of a record, you can add any other info as well.
