TXT is a DNS record, which contains information in human-readable form for external sources to gain info about a particular Internet domain or subdomain. In the most common situation, this sort of record is employed to prove that you own a domain in case you are trying to add it to a search engine or to some website traffic analytics platform. Since just the domain address owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the business supplying the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, that makes sure that an e-mail address will not be spoofed and that others will not get unsolicited mail from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages come from and functions as validation that it's a dependable one. Because there are no restrictions about the content of such a record, you could also include any other info also.
