I'll create a product updates email design with images and a call-to-action (CTA) button. This design will be responsive and use modern email-safe HTML and inline CSS for maximum compatibility across email clients.

Let's create the HTML email template:

This HTML email template includes:

1. A responsive design that works well on both desktop and mobile devices.
2. A header with a placeholder for your company logo.
3. Two product update sections, each with an image and description.
4. A prominent CTA button to encourage users to explore the new features.
5. A footer with social media links and company information.

To use this template:

1. Replace the placeholder images (/placeholder.svg?height=X&width=Y) with your actual product images and logo.
2. Update the text content to match your specific product updates.
3. Modify the colors to match your brand (e.g., the blue CTA button).
4. Add your actual social media links in the footer.
5. Test the email in various email clients to ensure compatibility.

This design provides a clean, professional look that highlights your product updates and encourages user engagement through the CTA button. The use of images helps to visually break up the content and make the email more appealing to readers.
