TXT is a DNS record, that contains information in human-readable form for external sources to obtain information regarding a specific Internet domain or subdomain. In the most common case, this sort of record is employed to prove that you own a domain name if you're trying to add it to an Internet search engine or to some web traffic analytics platform. Since just the domain address owner/administrator is able to add custom DNS records, the TXT record works as a verification of ownership for the company providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, which helps to ensure that an email address isn’t spoofed and that people will not receive unsolicited mail from allegedly your mailbox. The TXT record includes info about the mail server where your electronic messages come from and functions as validation that it's a trusted one. Since there are no standards concerning the content of this kind of a record, you could also include any other information also.
