TXT is a DNS record, that contains information in human-readable form for external sources to gain information regarding a particular Internet domain or subdomain. In the most common situation, such a record is used to prove that you own a domain name if you are trying to add it to an online search engine or to some site traffic analytics platform. As just the domain address owner/administrator may add custom DNS records, the TXT record serves as a proof of ownership for the firm offering the service. Another popular use for this kind of records is the email SPF (Sender Policy Framework) security, that makes sure that an email address won't be spoofed and that others will not get junk mail from allegedly your mailbox. The TXT record contains details about the mail server where your online messages come from and functions as confirmation that it's a dependable one. Since there are no regulations concerning the content of this type of a record, you could also include any other info as well.
