Sending a notification to the customer on their preferred channel

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

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 analysis of the results

This recipe shows step 3 of the campaign.

Once our codes are created for direct marketing, we need to distribute them to our customers.
