TXT is a DNS record, that contains data in human-readable form for external sources to get info about a specific domain 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 online search engine or to some site traffic analytics platform. Since just the domain owner/administrator may add custom DNS records, the TXT record functions as a proof of ownership for the firm supplying the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) protection, which helps to ensure that an e-mail address isn’t spoofed and that people will not receive spam from allegedly your mailbox. The TXT record includes info about the mail server where your electronic messages arrive from and serves as validation that it's a dependable one. Because there are no rules about the content of this sort of a record, you can include any other info as well.
