Why do we need the 'Google Drive' permission? First, we try to use as few permissions as possible. And if we need a new permission we have to send a request with reasoning to Google. They check then our source code to ensure that we are only doing what we need and allowed to do. We use the Google Drive permission to: 1.) handle filters in sheets and 2.) the main usage, to access custom email attachments - nothing more!

All other permissions are needed to establish the core functionality.

This application is free and has no functional limitations. The number of emails/day is NOT limited by GSM! The daily limit is defined by your Google Account!

The limits by Google are typically: 100/day for private accounts and 1500/day for business accounts. Please keep in mind: THIS LIMITS ARE DEFINED BY YOUR GOOGLE ACCOUNT - NOT BY GSM!

GSM. A powerful and easy to use email marketing solution for your business.
Happy mailing, klaus
