TXT is a DNS record, containing data in human-readable form for external sources to get information about a specific domain name or subdomain. In the most common scenario, this sort of record is employed to prove that you own a domain in case you're trying to add it to an online search engine or to some site traffic analytics platform. Due to the fact that only the domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the corporation supplying the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) protection, which ensures that an email address won't be spoofed and that people will not receive junk mail from allegedly your mailbox. The TXT record contains info about the mail server where your online messages come from and serves as verification that it's a trusted one. Because there are no restrictions concerning the content of this kind of a record, you can add any other information also.
