# PRIVACY & PERMISSIONS
We try to use as few permissions as possible and so GSM has no external communication or data exchange! Nothing leaves your account, except the emails you sent. All granted permissions (Drive, Sheets, Gmail, ...) are internal only - and GSM does not read your documents at all. 

Why do we need the Google Drive permission?
To handle filters in sheets and to support custom email attachments - nothing more! But, as mentioned above - we do not read your documents and we do not exchange data with other websites or services. 



# NOTES
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!

I run a statewide education program in New Jersey and use this add-on to facilitate communications and monthly newsletters to now over 4,000 involved educators. The add-on is simple, effective, free, and wonderfully supported. Klaus has quickly responded to requests for help or questions in the few occasions where they were needed. Great work and thank you for empowering my organization Klaus!

The description says that there are no limits but as soon as I tried it out the add-on told me that I has a 100 email per day limit. What a disappointment

The idea behind it is great, but I can't seem to get it working. Somehow I keep getting this error and don't understand why? The selected template couldn't be opened or you don't have access. Please reopen the dialog and send again.

It works great for a straight mass e-mail, but when I try to personalize the e-mail, I get the error message, "Your template includes a variable which is not available in your sheet." I have typed and re-typed, re-named, copied-and-pasted, and double-checked my draft e-mail as well as the spreadsheet and cannot find an error.

I loved this add-on. How can I schedule or email or control number of emails sent per minute or per second?

The add-on has worked very well for me in the past. However, I just recently started having an issue where it doesn't pull up my drafts from Gmail, even after logging out of my account and logging back in. Is there a fix?
