Permissions + roles

• Email Settings, Email Templates and Email Logs appear in the menu for staff with the View email permission. Opening Email Logs needs Manage settings.
• Notification Preferences needs Manage settings (or the notification-preferences permission).

Set permissions in Customers → User Groups. Give template editing only to people who should change what customers receive.

Sellers can't change the store's emails; they receive their own seller emails (new orders, payouts).
