TXT is a DNS record, containing data in human-readable form for external sources to obtain info about a particular domain or subdomain. In the most common situation, this sort of record is used to prove that you own a domain in case you are trying to add it to an Internet search engine or to some traffic analytics platform. Due to the fact that just the domain address owner/administrator may add custom DNS records, the TXT record functions as a verification of ownership for the business supplying the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which makes sure that a particular email address isn’t spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record features info about the mail server where your electronic messages come from and serves as confirmation that it's a reliable one. Since there are no restrictions concerning the content of such a record, you can include any other information also.
