TXT is a DNS record, containing information in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common situation, such a record is employed to prove that you own a domain if you are trying to add it to a search engine or to some 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 firm providing 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 shall not be spoofed and that individuals will not receive junk mail from allegedly your mailbox. The TXT record includes info about the mail server where your digital messages arrive from and serves as validation that it's a reliable one. Since there are no restrictions concerning the content of this type of a record, you could also include any other information as well.
