Understanding commercial email: Examples and best practices

Commercial email generates $10-$36 per $1 spent. That’s a pretty impressive ROI—if your carefully crafted campaigns don’t end up in the spam folder or break completely in dark mode. Commercial email refers to messages sent primarily to promote a product or service. While that sounds straightforward, the distinction between commercial versus transactional email isn’t just marketing jargon. It’s a necessary factor for legal compliance and deliverability success.
