Using GIFs or images can make emails feel more lively, but they need to support the message instead of distracting from it. A simple image can explain something faster than text, while a GIF can add a light moment or show a product in action. The challenge is that large images can load slowly or appear broken on some devices. Some email apps even block pictures by default, which can change the look of the message. Keeping visuals small and meaningful usually works best. Clear text should still carry the main message so the email remains useful even without images. What kind of visual style do you think keeps readers engaged without making the email feel too heavy?
