Gmail will clip your email design if your email size exceeds 102KB. Where the email is clipped there will be a link to view entire message. Selecting the link in the message will open a new window with the entire email downloaded.
How different platforms clip the email
Currently, for Android devices, there is no link for viewing the entire message.
The iPhone does display the link, it reads "[Message clipped] Download entire message", clicking this loads the entire message on the same window.
A link to view the entire message does not display. It remains cut off.
