TXT is a DNS record, that contains information in human-readable form for external sources to obtain info about a certain Internet domain or subdomain. In the most common case, 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 website traffic analytics platform. Since only the domain owner/administrator can add custom DNS records, the TXT record serves as a verification of ownership for the corporation providing the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, that ensures that an email address won't be spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record features info about the mail server where your electronic messages originate from and serves as verification that it is a reliable one. Because there are no regulations about the content of this type of a record, you can add any other information also.
