TXT is a DNS record, containing information in human-readable form for external sources to get information regarding a certain Internet domain or subdomain. In the most common scenario, 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 site traffic analytics platform. Since only the domain address owner/administrator is able to add custom DNS records, the TXT record works as a proof of ownership for the company providing the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) security, which helps to ensure that a particular email address won't be spoofed and that people will not receive spam from allegedly your mailbox. The TXT record includes details about the mail server where your electronic messages arrive from and functions as verification that it's a trusted one. Since there are no standards regarding the content of this type of a record, you can include any other information also.
