If you find that the GMass button in the Compose window is too big, then you can now set your account to have a smaller button. You may want to do this if you have other Gmail extensions installed which are taking space along the main button bar in the Compose window, or if you are getting a horizontal scroll bar in the Compose window.
To control the size of the GMass button:

- Ensure you have the latest GMass extension from the Chrome Web Store. You should have version 2.0.0 or higher. If you don’t, point Chrome to chrome://extensions and click the Update extensions now button in the upper right.
- Reload Gmail.
- Click Compose to launch a new window.
- Set the To field to button@gmass.co.
- Set the Subject to “small” or “big”.
- Hit the GMass button. Do not hit the Send button.
- Reload Gmail.
The button size will be set for your account. You will need to re-load Gmail for the change to take effect. If you set your button to “small”, this is what it will look like:
