TXT is a DNS record, that contains information in human-readable form for external sources to get info about a particular domain or subdomain. In the most common situation, this type of record is employed to prove that you own a domain name if you are trying to add it to an Internet search engine or to some traffic analytics platform. Due to the fact that only the Internet domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the corporation supplying the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) protection, which ensures that a particular email address won't be spoofed and that individuals will not get junk e-mail from allegedly your mailbox. The TXT record contains info about the mail server where your online messages come from and serves as proof that it is a reliable one. Because there are no rules regarding the content of this type of a record, you can include any other info also.
