With a significant number of users opening emails on mobile devices, it is essential to optimize your HTML emails for smaller screens. Here are some tips:
Use a responsive design to ensure that the email adjusts to different screen sizes. Keep the email width to around 600px for better readability on mobile devices. Use larger fonts and buttons to make it easier for users to read and interact with the email. Test the email on various mobile devices to make sure it looks good and functions properly.
