TXT is a DNS record, containing information in human-readable form for external sources to obtain information about a particular domain or subdomain. In the most common scenario, this type of record is employed to prove that you own a domain name in case you are trying to add it to a search engine or to some traffic analytics platform. As just the domain owner/administrator can add custom DNS records, the TXT record works as a proof of ownership for the business providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, that makes sure that an e-mail address will not be spoofed and that people will not get spam from allegedly your mailbox. The TXT record includes details about the mail server where your electronic messages come from and serves as validation that it's a trusted one. Because there are no rules regarding the content of this sort of a record, you could add any other information also.
