Gmail clips messages exceeding 102K
If your email exceeds 102K, Gmail will display the first 102K along with a message that reads:
[Message clipped] View entire message
When the user clicks to view the entire message, your email will be displayed in a new window.
If you are close to 102K, you might save a few bytes by removing any unnecessary spaces, carriage returns or comments.
We recommend that you avoid embedded images and documents when sending HTML emails.
