TXT is a DNS record, that contains data in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common scenario, this kind of record is employed to prove that you own a domain name if you are trying to add it to an online search engine or to some web traffic analytics platform. Due to the fact that just the Internet domain owner/administrator can add custom DNS records, the TXT record works as a proof of ownership for the firm providing the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) security, which ensures that an e-mail address will not be spoofed and that others will not receive junk mail from allegedly your mailbox. The TXT record contains info about the mail server where your online messages originate from and functions as validation that it's a dependable one. Since there are no standards concerning the content of this sort of a record, you can include any other info as well.
