How do I send an email using the old Gmail compose window?
By default, Mixmax will send messages from Gmail's compose window. With Mixmax 2.0, all of the features your'e used to will be available natively in the Gmail window. If you need to send a message without Mixmax at all you can temporarily disable Mixmax in your account. You can learn more about how to disable Mixmax in your email here.
