TXT is a DNS record, containing data in human-readable form for external sources to get information regarding a certain domain name or subdomain. In the most common case, this sort of record is used to prove that you own a domain name if you are trying to add it to an Internet search engine or to some site traffic analytics platform. Considering that just the domain owner/administrator can add custom DNS records, the TXT record works as a verification of ownership for the company offering the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) protection, that helps to ensure that an email address will not be spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record contains info about the mail server where your online messages originate from and functions as confirmation that it is a dependable one. As there are no rules regarding the content of this sort of a record, you can include any other info also.
