TXT is a DNS record, containing information in human-readable form for external sources to obtain info about a particular Internet domain or subdomain. In the most common situation, this sort of record is employed to prove that you own a domain in case you are trying to add it to an online search engine or to some traffic analytics platform. Considering that only the Internet domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the firm supplying the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, which ensures that an e-mail address shall not be spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record contains info about the mail server where your electronic messages originate from and functions as validation that it is a trusted one. As there are no standards regarding the content of this sort of a record, you could add any other info also.
