TXT is a DNS record, that contains information in human-readable form for external sources to get information regarding a certain Internet domain or subdomain. In the most common situation, such a record is employed to prove that you own a domain name in case you're trying to add it to a search engine or to some web traffic analytics platform. Due to the fact that only the domain address owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the firm providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) protection, that makes sure that an e-mail address won't be spoofed and that individuals will not receive unsolicited mail from allegedly your mailbox. The TXT record includes information about the mail server where your online messages originate from and functions as proof that it's a trusted one. Since there are no regulations about the content of this sort of a record, you could also include any other information as well.
