TXT is a DNS record, containing information in human-readable form for external sources to obtain info about a certain domain name or subdomain. In the most common situation, this kind of record is used to prove that you own a domain if you are trying to add it to a search engine or to some traffic analytics platform. Considering that only the domain owner/administrator is able to add custom DNS records, the TXT record works as a verification of ownership for the business supplying the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) security, which ensures that an email address will not be spoofed and that individuals will not receive unsolicited mail from allegedly your mailbox. The TXT record features information about the mail server where your digital messages come from and serves as proof that it is a reliable one. Since there are no standards regarding the content of this sort of a record, you can include any other information as well.
