Email addresses issued by free email service providers are unlikely to be linked to corporate accounts and business leads.
Temporary email addresses are supplied by email service providers like Mailinator, GuerrillaMail, or 2,000+ others. They are created for short-term purposes in mind and can be fraudulent.
Branded email addresses are typically accompanied by a valid domain that has its DNS MX records properly configured.
