There are two kinds of email classifications: commercial and non-commercial. What types of emails fit into these classifications varies from country to country. For example, in some jurisdictions, commercial email could include advertisements or promotions of a commercial product or service, while billing statements and invoices would be considered non-commercial emails.

In Salesforce, reps can send commercial emails only to recipients who have not selected to opt of commercial emails. Recipients whose email privacy preferences are set to Do Not Market in the data privacy record based on the Individual object can be sent only non-commercial emails. Only reps with the Send Non-Commercial Email permission can send non-commercial emails.

Because marketing and privacy laws vary in different countries, you should consult with a legal expert in determining how to apply the commercial and non-commercial email classifications.
