Gmail email invoices

SUGGESTED

I am looking to send my invoice from Sage through my Gmail email account, but I don't want it to be sent right away. I would prefer it was saved into my Out Box so that I could review and make changes. I also need to add a file to the email that needs to be sent to the customer. I currently have it setup to send the email, but it send it right away. Anyone know how I can have it stopped from being sent.

Thanks,
