TXT is a DNS record, which contains data in human-readable form for external sources to gain information about a certain domain or subdomain. In the most common case, this type of record is used to prove that you own a domain in case you're trying to add it to an online search engine or to some web traffic analytics platform. Since just the domain name owner/administrator can add custom DNS records, the TXT record serves as a proof of ownership for the business supplying 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 e-mail address isn’t spoofed and that people will not get junk mail from allegedly your mailbox. The TXT record features info about the mail server where your electronic messages arrive from and functions as validation that it is a dependable one. Because there are no rules regarding the content of this type of a record, you can include any other information also.
