This allows the system to send emails directly to your clients and suppliers via your email system instead of using the system's one.
When sending out emails Zigaflow will automatically use the correct email account that matches the email address entered in the "From:" field in the quote or invoice, etc.
If no matching email address is found, then the default email account is used.
Where to find the Settings in Zigaflow
Select the cog at the top right of the Zigaflow screen, then Email Management
