Optimizing assets ensures that your emails load quickly and look good on various devices. Here’s how you can optimize different types of assets:
Images: Compress images using tools like TinyPNG or JPEG-Optimizer. Use the correct format (JPEG for photos, PNG for graphics). Videos: Instead of embedding videos, use a linked thumbnail that directs users to a landing page where they can view the video. Templates: Utilize responsive email templates to ensure your emails look great on both desktop and mobile devices. Fonts: Use web-safe fonts or host custom fonts to ensure they render correctly in different email clients.
