TXT is a DNS record, containing info in human-readable form for external sources to get information about a particular domain or subdomain. In the most common situation, this sort of record is employed to prove that you own a domain if you are trying to add it to an Internet search engine or to some traffic analytics platform. As only the Internet domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the company providing the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) protection, that ensures that an e-mail address shall not be spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record features details about the mail server where your online messages arrive from and functions as confirmation that it's a reliable one. Since there are no restrictions regarding the content of this type of a record, you can include any other information also.
