TXT is a DNS record, containing data in human-readable form for external sources to gain info about a specific domain name or subdomain. In the most common situation, this type of record is used to prove that you own a domain if you're trying to add it to an online search engine or to some web traffic analytics platform. Considering that only the domain address owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the company supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, which makes sure that a particular email address won't be spoofed and that individuals will not receive unsolicited mail from allegedly your mailbox. The TXT record features details about the mail server where your online messages come from and serves as confirmation that it is a reliable one. Since there are no restrictions about the content of this kind of a record, you could also include any other information also.
