TXT is a DNS record, that contains information in human-readable form for external sources to get info about a specific domain or subdomain. In the most common situation, this kind of 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 website traffic analytics platform. Considering that only the domain address owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the firm supplying 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 won't be spoofed and that people will not receive unsolicited mail from allegedly your mailbox. The TXT record includes information about the mail server where your online messages originate from and functions as proof that it's a dependable one. As there are no regulations regarding the content of this sort of a record, you could also include any other information also.
