Creating personalized coupon codes

In this chapter, we are presenting a marketing campaign divided into several tasks:

1. Detect the best moment to launch the campaign
2. Generate individual codes to be sent to potential customers
3. Send the codes directly to users over their preferred channel, text message or email
4. Collect the results of the campaign
5. Generate a sales report with an analysis of the results

This recipe shows task 2 of the campaign.

After an opportunity has been detected, we decide to generate a campaign for all customers. To direct promotions and avoid duplication, we will generate 1 million unique coupons, divided into three batches:

• Half of the codes will be printed and distributed in a marketing action.
• 300,000 codes will be reserved to be used later if the campaign hits some goals.
• The remaining 200,000 will be directed to customers through SMS and emails.

These coupons can be redeemed...
