TXT is a DNS record, which contains information in human-readable form for external sources to gain info about a specific domain or subdomain. In the most common case, this type of record is used 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. Since just the domain owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the firm supplying 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 e-mail address will not be spoofed and that individuals will not get spam from allegedly your mailbox. The TXT record features details about the mail server where your digital messages arrive from and functions as confirmation that it's a trusted one. As there are no regulations regarding the content of this type of a record, you could add any other info as well.
