TXT is a DNS record, which contains data in human-readable form for external sources to obtain info about a specific domain name or subdomain. In the most common case, this sort of record is used to prove that you own a domain in case you're trying to add it to an Internet search engine or to some site traffic analytics platform. Due to the fact that just the Internet domain owner/administrator is able to add custom DNS records, the TXT record functions as a verification of ownership for the company providing the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, that makes sure that an e-mail address will not be spoofed and that individuals will not receive spam from allegedly your mailbox. The TXT record includes info about the mail server where your online messages originate from and functions as validation that it is a dependable one. Since there are no standards about the content of this sort of a record, you can include any other information also.
