TXT is a DNS record, which contains info in human-readable form for external sources to obtain information regarding a certain domain name or subdomain. In the most common situation, such a record is used to prove that you own a domain in case you're trying to add it to an Internet search engine or to some site traffic analytics platform. Due to the fact that only the domain name owner/administrator can add custom DNS records, the TXT record functions as a verification of ownership for the business supplying the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which helps to ensure that an email address won't be spoofed and that people will not get unsolicited mail from allegedly your mailbox. The TXT record contains info about the mail server where your digital messages arrive from and functions as proof that it is a trusted one. Since there are no rules concerning the content of this sort of a record, you could also include any other info as well.
