TXT is a DNS record, containing data in human-readable form for external sources to obtain information regarding a particular domain name or subdomain. In the most common case, such a record is employed to prove that you own a domain name in case you're trying to add it to an Internet search engine or to some traffic analytics platform. As just the domain name owner/administrator can add custom DNS records, the TXT record serves as a verification of ownership for the business offering the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which makes sure that an email address will not be spoofed and that individuals will not get junk e-mail from allegedly your mailbox. The TXT record includes information about the mail server where your electronic messages arrive from and functions as validation that it's a reliable one. As there are no restrictions regarding the content of this type of a record, you could also include any other information also.
