TXT is a DNS record, that contains info in human-readable form for external sources to get information about a particular domain name or subdomain. In the most common scenario, this type of record is used to prove that you own a domain name in case you're trying to add it to an Internet search engine or to some traffic analytics platform. Due to the fact that only the Internet domain owner/administrator can add custom DNS records, the TXT record functions as a proof of ownership for the company offering the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) protection, which helps to ensure that an email address won't be spoofed and that others will not receive junk mail from allegedly your mailbox. The TXT record contains information about the mail server where your electronic messages come from and serves as verification that it is a trusted one. As there are no restrictions about the content of this sort of a record, you can include any other info as well.
