Enter the settings required for your Email SMTP Server:
Default Emails Per Batch - Allows you to throttle back how many emails go out per batch.
Default Seconds Per Batch - Allows you to configure a break between batches.
Copy to All Regions - This will copy these default settings to all Regions.
Set All Notifications to Default Batch - Sets all notifications to the Batch Totals Configured Above (these can be customized for any email)
Gmail - DO NOT CHECK THIS for App Password Configurations, this is only for OAuth Configurations and is significantly more complicate to configure on the Google Side.
