TXT is a DNS record, that contains information in human-readable form for external sources to get information about a specific Internet domain or subdomain. In the most common case, such a record is employed to prove that you own a domain if you are trying to add it to an Internet search engine or to some website traffic analytics platform. Considering that only the domain address owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the firm offering the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) security, that helps to ensure that an email address shall not be spoofed and that individuals will not receive junk mail from allegedly your mailbox. The TXT record includes details about the mail server where your electronic messages come from and functions as validation that it's a reliable one. Because there are no restrictions about the content of this sort of a record, you could also include any other information also.
