TXT is a DNS record, which contains data in human-readable form for external sources to obtain information about a particular domain name or subdomain. In the most common scenario, this type of record is used to prove that you own a domain name in case you're trying to add it to a search engine or to some traffic analytics platform. As just the domain name 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 kind of records is the e mail SPF (Sender Policy Framework) security, that helps to ensure that an email address isn’t spoofed and that people will not receive junk mail from allegedly your mailbox. The TXT record contains info about the mail server where your electronic messages come from and serves as verification that it is a trusted one. Because there are no regulations regarding the content of this sort of a record, you could add any other information also.
