TXT is a DNS record, containing data in human-readable form for external sources to obtain information regarding a specific domain name 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 Internet search engine or to some traffic analytics platform. Since just the Internet domain owner/administrator may add custom DNS records, the TXT record works as a proof of ownership for the business providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, that helps to ensure that an e-mail address will not be spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record contains details about the mail server where your electronic messages come from and functions as proof that it's a dependable one. Because there are no rules regarding the content of this sort of a record, you could also include any other info as well.
