Mobile optimization and email deliverability are critical success factors for small business email marketing. This section covers mobile usage, design best practices, and technical requirements.
Mobile email dominance has fundamentally shifted email design priorities for small business marketers. With most subscribers reading on phones, mobile-first design is no longer optional but essential for engagement and deliverability.
