TXT is a DNS record, which contains data in human-readable form for external sources to get information about a specific domain or subdomain. In the most common scenario, this kind of record is used to prove that you own a domain if you're trying to add it to an online search engine or to some site traffic analytics platform. Due to the fact that only the domain address owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the corporation supplying the service. Another popular use for this kind of records is the e-mail SPF (Sender Policy Framework) security, that makes sure that an email address isn’t spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record includes info about the mail server where your digital messages come from and serves as confirmation that it is a reliable one. Because there are no rules regarding the content of this type of a record, you could also include any other information also.
