TXT is a DNS record, which contains info in human-readable form for external sources to obtain info about a particular domain or subdomain. In the most common situation, this sort of record is used to prove that you own a domain if you are trying to add it to an Internet search engine or to some website traffic analytics platform. Since only the domain name owner/administrator can add custom DNS records, the TXT record works as a verification of ownership for the company offering the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) security, that helps to ensure that a particular email address won't be spoofed and that individuals will not get junk mail from allegedly your mailbox. The TXT record includes details about the mail server where your electronic messages arrive from and functions as validation that it is a trusted one. As there are no standards concerning the content of this kind of a record, you can add any other info also.
