First, you'd need to create your discount code using Shopify. Here's a nice tutorial for that: https://help.shopify.com/en/manual/discounts/create-discount-codes
Second, you need to add the discount code in the link and have the discounts auto-apply when a customer enters your store from the links.
You can achieve this using an app https://apps.shopify.com/discount-on-cart-pro and then appending `?discount-code=YOUR-CODE` to the URLs that you send.
That will do one of two things:
- If the customer already has items in their cart, the coupon will be applied and a success message will show the discount amount.
- If the cart is empty, the app will attempt to apply the coupon once the customer adds something to their cart.
The coupon application would happen on any page which displays either the app's standalone discount field or the app's discount coupon cart summary.
There are two steps involved in sending contact discount codes; you can add coupon codes to your list and send coupon codes to your contacts.
Step 1: Enter coupon codes in your Mailchimp list
Step 2: Sends coupon codes to your Mailchimp subscribers
Now that the coupon codes are in your Mailchimp list, we can send a different code to each contact. Here are the steps:
Each subscriber will now receive an email message with a corresponding coupon code.
Sending a discount to new subscribers is a good way to welcome potential clients!
