Clear Messaging: Clearly explain the offer in the email body. Highlight the value and urgency. 3. Eye-Catching Design: Use high-quality images and a clean layout to make the offer stand out. 4. Strong Call-to-Action (CTA): Include a prominent CTA button such as "Shop Now" to direct recipients to your website.
