I know when creating email campaigns, you can choose what email is used as the sender:



But for a sign-up form, I don't see any obvious way to choose what email is used to respond to users with confirmation emails when creating a signup form that saves contacts to a custom contact list?

It always uses the Zoho main account email, can't really expect me to change my main account email for this to work? I may want to use different emails as a sender for different signup forms.??
