TXT is a DNS record, which contains data in human-readable form for external sources to get information regarding a particular domain or subdomain. In the most common case, such a record is used to prove that you own a domain name if you are trying to add it to an online search engine or to some website traffic analytics platform. Due to the fact that just the Internet domain owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the corporation providing the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which helps to ensure that a particular email address will not be spoofed and that individuals will not get junk mail from allegedly your mailbox. The TXT record includes information about the mail server where your online messages come from and functions as confirmation that it's a trusted one. As there are no regulations concerning the content of this type of a record, you could also include any other info as well.
