In PushSend we have the concept of Campaigns and Emails. A campaign is a marketing effort that uses email to deliver messages to your target audience. Think of the Campaign as a shell, which can contain multiple emails. So, for example, you could have a Campaign for your upcoming sale, and within that campaign you might have 3-4 emails promoting the sale at different stages.
This video will show you how to create a campaign and then create an email within the campaign.
