TXT is a DNS record, that contains information in human-readable form for external sources to get information regarding a certain Internet domain or subdomain. In the most common situation, 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. Considering that just the domain address owner/administrator can add custom DNS records, the TXT record serves as a proof of ownership for the firm offering the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which ensures that an e-mail address isn’t spoofed and that people will not get junk mail from allegedly your mailbox. The TXT record contains info about the mail server where your digital messages originate from and functions as proof that it's a trusted one. As there are no restrictions concerning the content of this sort of a record, you could also include any other information as well.
