TXT is a DNS record, which contains info in human-readable form for external sources to gain info about a particular domain name or subdomain. In the most common situation, this sort of record is employed to prove that you own a domain name in case you're trying to add it to a search engine or to some website traffic analytics platform. Considering that just the domain name owner/administrator may add custom DNS records, the TXT record works as a proof of ownership for the firm supplying the service. Another popular use for this type of records is the e mail SPF (Sender Policy Framework) security, which makes sure that a particular email address shall not be spoofed and that individuals will not receive junk mail from allegedly your mailbox. The TXT record contains info about the mail server where your electronic messages arrive from and serves as confirmation that it is a trusted one. Since there are no regulations about the content of this kind of a record, you can add any other info also.
