How many campaigns, steps, and products can I have?

• Up to 25 campaigns live at once.
• Up to 20 discount steps per campaign.
• Up to 5 build-a-box sections per campaign.
• Up to 150 items in a fixed bundle's contents.

Campaigns also have compiled-size limits. The Publish step warns when a campaign is getting large, and Diagnostics shows the detailed size information. Targeting collections instead of long lists of individual variants can keep campaign data smaller.
