TXT is a DNS record, containing information in human-readable form for external sources to obtain information regarding a particular Internet domain or subdomain. In the most common case, such a record is employed to prove that you own a domain in case you're trying to add it to an Internet search engine or to some traffic analytics platform. Considering that just the domain owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the firm providing the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, which helps to ensure that a particular email address won't be spoofed and that individuals will not receive junk e-mail from allegedly your mailbox. The TXT record includes information about the mail server where your online messages originate from and functions as proof that it is a trusted one. As there are no standards concerning the content of this sort of a record, you can include any other info also.
