Following coding standards is crucial for several reasons:
Cross-Client Compatibility: Different email clients (e.g., Gmail, Outlook, Yahoo) render HTML emails differently. Adhering to coding standards helps ensure that your emails look consistent across all platforms. Mobile Responsiveness: With a significant portion of users now checking emails on their mobile devices, it's vital to follow standards that guarantee your emails are mobile-friendly. Accessibility: Ensuring your emails are accessible to people with disabilities is not just ethically important but also broadens your reach. Deliverability: Proper coding can help in avoiding spam filters, thereby improving your email deliverability rates.
