TXT is a DNS record, that contains data in human-readable form for external sources to get information regarding a particular domain or subdomain. In the most common situation, such a 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. As just the domain name owner/administrator is able to add custom DNS records, the TXT record functions as a verification of ownership for the company providing the service. Another popular use for this sort of records is the e mail SPF (Sender Policy Framework) security, which makes sure that an email address isn’t spoofed and that others will not receive junk e-mail from allegedly your mailbox. The TXT record contains info about the mail server where your electronic messages arrive from and serves as validation that it is a dependable one. As there are no rules about the content of this type of a record, you can include any other info as well.
