TXT is a DNS record, that contains info in human-readable form for external sources to get information about a certain Internet domain or subdomain. In the most common situation, this sort of record is used to prove that you own a domain in case you are trying to add it to an online search engine or to some web traffic analytics platform. Since just the Internet domain owner/administrator may add custom DNS records, the TXT record works as a verification of ownership for the corporation supplying the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) protection, that makes sure that a particular email address will not be 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 online messages arrive from and serves as confirmation that it is a dependable one. Since there are no restrictions about the content of this sort of a record, you could also include any other info as well.
