TXT is a DNS record, which contains info in human-readable form for external sources to obtain information regarding a certain domain or subdomain. In the most common case, this kind of record is employed to prove that you own a domain name if you're trying to add it to an Internet search engine or to some traffic analytics platform. Since just the domain name owner/administrator may add custom DNS records, the TXT record works as a proof of ownership for the firm offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, that helps to ensure that an e-mail address isn’t spoofed and that others will not get junk e-mail from allegedly your mailbox. The TXT record contains details about the mail server where your electronic messages come from and serves as validation that it is a trusted one. Because there are no restrictions regarding the content of this kind of a record, you can include any other info as well.
