TXT is a DNS record, containing data in human-readable form for external sources to obtain information regarding a specific domain name or subdomain. In the most common case, this sort of record is used to prove that you own a domain name if you are trying to add it to an Internet search engine or to some traffic analytics platform. Due to the fact that just the domain address owner/administrator may add custom DNS records, the TXT record works as a verification of ownership for the company offering the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) protection, which helps to ensure that an email address shall not be spoofed and that others will not get junk e-mail from allegedly your mailbox. The TXT record contains information about the mail server where your digital messages come from and functions as confirmation that it's a trusted one. Since there are no rules regarding the content of this sort of a record, you could add any other information also.
