TXT is a DNS record, that contains information in human-readable form for external sources to gain information about a specific Internet domain or subdomain. In the most common scenario, this sort of record is used to prove that you own a domain in case you're trying to add it to an online search engine or to some website traffic analytics platform. As just the domain name owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the company offering the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) security, that helps to ensure that a particular email address will not be spoofed and that others will not get junk mail from allegedly your mailbox. The TXT record contains details about the mail server where your digital messages arrive from and serves as validation that it's a reliable one. As there are no restrictions regarding the content of this sort of a record, you could also include any other info also.
