TXT is a DNS record, that contains data in human-readable form for external sources to gain info about a particular domain or subdomain. In the most common scenario, this kind of record is employed to prove that you own a domain if you're trying to add it to a search engine or to some web traffic analytics platform. Considering that just the domain address owner/administrator can 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, that helps to ensure that an e-mail address isn’t spoofed and that others will not receive spam from allegedly your mailbox. The TXT record features information about the mail server where your digital messages originate from and serves as proof that it's a reliable one. As there are no rules concerning the content of this sort of a record, you can include any other info also.
