TXT is a DNS record, containing information in human-readable form for external sources to obtain information about a particular Internet domain or subdomain. In the most common scenario, such a record is used to prove that you own a domain in case you're trying to add it to an online search engine or to some web traffic analytics platform. As just the domain owner/administrator is able to add custom DNS records, the TXT record functions as a verification of ownership for the firm supplying the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) security, which ensures that a particular email address won't be spoofed and that others will not get junk mail from allegedly your mailbox. The TXT record features info about the mail server where your electronic messages come from and serves as confirmation that it is a reliable one. Because there are no restrictions concerning the content of this kind of a record, you could add any other info as well.
