You can monitor your email communication with your clients and see what they are receiving by setting up an auto-BCC (blind carbon copy) to yourself on every email sent from Sprout Studio.
How to turn on BCC
Go to Settings > Account & Branding > Preferences and turn the "Auto BCC" toggle to ON. Once this happens the "Auto BCC email" field will become active and you can enter the email you would like copied.
By default, the email address listed in your Profile will be auto-BCC'd on all outgoing emails from Sprout Studio if this field is left blank when turned on. If you prefer a different email address, specify it in the "Auto BCC Email" box.
