Campaign Explained In Details {% embed url="" %} The main idea of a campaign is to group multiple discounts together, allowing them to work in unison. However, it is not mandatory to have multiple discounts within a campaign. In some cases, you might want to have just one discount, such as a volume discount. All properties of a campaign apply to every discount within that campaign. Campaigns always have active dates: a start date and an end date. If you do not specify an end date, the campaign will never expire. You can disable, enable, or delete a campaign at any time. There are two types of campaigns: Automatic and Campaign Code. Automatic Campaigns function automatically for all customers.
For Campaign Code campaigns, you specify a campaign code that customers need to apply for the campaign to take effect. When a customer applies the campaign code, all discounts within that campaign become functional. You can also specify customer eligibility and set a maximum number of times the discount can be used.
After creating a campaign, the app will generate a special type of discount in your Shopify admin discounts page.
Please never modify or delete these discounts from the Shopify Discounts page. Perform all your actions directly from the app.
