TXT is a DNS record, that contains information in human-readable form for external sources to obtain information regarding a particular domain or subdomain. In the most common scenario, such a record is employed to prove that you own a domain name in case you're trying to add it to an Internet search engine or to some site traffic analytics platform. Due to the fact that just the domain address owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the firm offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, which helps to ensure that a particular email address shall not be spoofed and that individuals will not receive spam from allegedly your mailbox. The TXT record contains details about the mail server where your digital messages arrive from and serves as verification that it is a reliable one. As there are no restrictions about the content of this kind of a record, you can include any other information also.
