TXT is a DNS record, containing info in human-readable form for external sources to gain info about a particular Internet domain or subdomain. In the most common scenario, this type of record is employed to prove that you own a domain if you're trying to add it to an online search engine or to some website traffic analytics platform. As only the domain owner/administrator can add custom DNS records, the TXT record works as a verification of ownership for the firm offering the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, that ensures that a particular email address will not be spoofed and that others will not receive spam from allegedly your mailbox. The TXT record contains details about the mail server where your online messages come from and functions as verification that it's a dependable one. As there are no rules regarding the content of this sort of a record, you can add any other info also.
