To optimize MIME for email marketing, follow these best practices:
Use Alt Text: Always include alt text for images to ensure that your message is still conveyed even if the images don't load. Keep it Simple: Avoid overloading your email with too many media elements, as this can slow down loading times and affect user experience. Test Across Devices: Ensure that your MIME emails render correctly across different email clients and devices to provide a consistent experience. Monitor Deliverability: Track your email deliverability rates to ensure that your MIME-encoded emails are not being flagged as spam.
