TXT is a DNS record, that contains data in human-readable form for external sources to gain information about a specific Internet domain or subdomain. In the most common case, such a record is used 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. Considering that only the domain name owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the firm offering the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, which helps to ensure that an e-mail address won't be spoofed and that others will not get unsolicited mail from allegedly your mailbox. The TXT record features information about the mail server where your online messages come from and serves as validation that it's a dependable one. Since there are no rules about the content of this sort of a record, you can include any other information as well.
