TXT is a DNS record, that contains info in human-readable form for external sources to get info about a specific domain name or subdomain. In the most common case, this kind of record is employed to prove that you own a domain if you're trying to add it to an Internet search engine or to some website traffic analytics platform. As just the domain address owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the business offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, which helps to ensure that an email address will not be spoofed and that people will not receive junk e-mail from allegedly your mailbox. The TXT record features info about the mail server where your digital messages originate from and serves as confirmation that it's a reliable one. As there are no rules about the content of this type of a record, you can add any other info also.
