TXT is a DNS record, that contains information in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common case, this type of record is employed to prove that you own a domain name in case you're trying to add it to a search engine or to some site traffic analytics platform. Considering that only the Internet domain owner/administrator may add custom DNS records, the TXT record serves as a verification of ownership for the corporation offering the service. Another popular use for this sort of records is the e-mail SPF (Sender Policy Framework) security, which helps to ensure that an email address won't be spoofed and that others will not get junk e-mail from allegedly your mailbox. The TXT record features details about the mail server where your electronic messages arrive from and functions as confirmation that it is a trusted one. Since there are no regulations concerning the content of this sort of a record, you could add any other info as well.
