TXT is a DNS record, which contains data in human-readable form for external sources to gain information regarding a certain domain or subdomain. In the most common situation, this kind of record is employed to prove that you own a domain name in case you are trying to add it to an Internet search engine or to some website traffic analytics platform. As just the domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the company supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, that helps to ensure that an email address isn’t spoofed and that people will not receive junk e-mail from allegedly your mailbox. The TXT record features information about the mail server where your digital messages originate from and serves as validation that it's a trusted one. Since there are no rules about the content of this sort of a record, you could add any other information also.
