Step 2: Choose your audience

When you create a campaign, you choose a segment to send that campaign to. A segment is a group of your contacts that share certain attributes. For example, a segment might contain all of your contacts who use version 2.0 of your app on an Android device, or all contacts who live in the city of Los Angeles.

Before you begin, complete Step 1: Add campaign details.

To specify a campaign sub-type

1. In this step, you have to choose a campaign sub-type. You can create two sub-types of campaigns in MoonMail:

  • Standard campaign – Choose this option if you want to send a campaign with a single message.
  • A/B test campaign – Choose this option if you want to create two or more separate variations of a message and send them to your contacts. Each of these versions is called a treatment. Choose Add another treatment to create an additional treatment. You can create between two and five treatments. Give each treatment a unique name that helps you identify it, and then specify the percentage of contacts in the segment that should receive each treatment. As you set the allocation of contacts who will receive each treatment, the Total holdout value adjusts to show the number of contacts who will not receive messages from this campaign.
To specify a segment
2. On the  Campaign audience page, choose an existing Segment to send your campaign to it. If you haven't created a segment yet follow the instructions in the Segments section to do so.
3. (Optional) Under Segment hold-out, specify the percentage of segment members who shouldn't receive this campaign. MoonMail chooses the appropriate number of segment members at random and omits them from the campaign.

You can use this feature to perform hold-out testing. In a hold-out test, you omit a sample group of random contacts and then compare their behaviors (for example, the number of purchases they make) against the behaviors of the contacts who received the campaign. In this way, you can determine the effectiveness of your campaigns.
