TXT is a DNS record, that contains info in human-readable form for external sources to get info about a particular Internet domain or subdomain. In the most common scenario, such a record is used to prove that you own a domain name if you are trying to add it to an online search engine or to some site traffic analytics platform. Due to the fact that just the domain owner/administrator is able to add custom DNS records, the TXT record functions as a proof of ownership for the business providing the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) security, that makes sure that a particular email address will not be spoofed and that individuals will not receive junk mail from allegedly your mailbox. The TXT record includes details about the mail server where your online messages come from and functions as proof that it's a dependable one. As there are no regulations regarding the content of this kind of a record, you could add any other information as well.
