A draft campaign is a campaign that has been scheduled to send at a to-be-determined future date. When you save a campaign as a draft, your campaign will be immediately uploaded to our e3 Delivery Service servers, but will not be sent until you actually schedule a delivery date. If you are using the Pay Per Email plan, credits for your delivery campaign will be deducted from your credit balance up front. If you later cancel delivery, those credits will be refunded back to your account.
To schedule a draft campaign for delivery, find the campaign in the Reports tab, then click the Schedule Delivery button.
