TXT is a DNS record, that contains information in human-readable form for external sources to get 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 are trying to add it to an online search engine or to some site traffic analytics platform. Due to the fact that just the Internet domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the company supplying the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, that ensures that an e-mail address won't be spoofed and that individuals will not receive spam from allegedly your mailbox. The TXT record features info about the mail server where your online messages originate from and serves as proof that it is a trusted one. As there are no restrictions regarding the content of such a record, you could also include any other info also.
