Send out a unique codes to new MailChimp subscribers using Coupon Carrier

If you run an online business you’ve probably used discount codes to attract more sales. Most E-Commerce solutions allow you to create discount codes with specific discounts like 10% or $10 off your purchase.

Many business owners would like to give new subscribers a discount code as an incentive when they join their MailChimp list. The problem is that you don’t want to give out the same code to all your customers since it’s likely that they will share it with others, which isn’t what you want.

You can often generate a large list of unique discount codes in your store but how do you distribute these to your subscribers so that each new subscriber receives one of those unique codes that you generated?

So how can I distribute my unique codes?

Coupon Carrier allows you to upload a list of unique codes and then monitor your MailChimp list for new subscribers. When a new subscriber is added it will pick one of the available unique codes from the list and then send out an email containing the code to the subscriber. Think of Coupon Carrier like a mailman who gives out discount codes.

This means that Coupon Carrier can’t generate the codes for you and it also can’t change how or if they work in your store. It only distributes the codes that you provide so you need to make sure that they will work once the subscribers receives them.

How to get started with Coupon Carrier

Create your Coupon Carrier account

If you don’t already have an account you can create one at Each new account receives 25 credits to be used for testing purposes. Credits are used when you add unique codes into Coupon Carrier. So if you add a list of 100 codes you would need 100 credits. The credits are sold in bulk packages and prices are available at

Connect your MailChimp account

The first time you login you will be prompted to connect Coupon Carrier to your MailChimp account in order for the integration to work. When you click to connect you will be redirected to MailChimp where you authorize the connection with your MailChimp credentials.

Choose how you want to distribute your codes

When you’ve connected your MailChimp you have the option to choose how you want to distribute your codes. We have two ways. One is using a Welcome Email described in this guide and the other one is the Redeem Link which you can read more about here.

In this case you want to use the Welcome Email feature so select that. This feature monitors your list constantly for new subscribers and then emails them a unique code. Which is what we want. Welcome Guide When you’ve selected to use the Welcome Email feature you will have the option to let Coupon Carrier create a test list in your MailChimp account and subscribe you to it so that you can receive an email with a sample code. You can also choose to skip this step.

Select your list and customize your email

Choose which of your lists you’d like to monitor for new subscribers. The optional dropdown labeled Store codes in a subscriber merge field can be enabled if you’d like Coupon Carrier to not only send out an email with the code but also store the code on the subscriber profile in a specified merge field. You can leave this at the default unless you’re certain that this is something you want.

Email settings allows you to choose how you’d like to send out the email. The first option is to have Coupon Carrier send out the email, which is what we want so this option should be selected. The other option is if you have a MailChimp automation that you’d like to be triggered for new subscribers (advanced). You can read more about triggered welcome emails here.

Select list

The next step is to customize the email by clicking the button labeled Customize your email content. This is where you configure your email subject, sender details and content. Remember to save your changes when you’re happy with the settings.

Add your list of unique codes

The integration is now configured and the last step before testing everything is to make sure that you’ve added some unique codes, Otherwise Coupon Carrier has nothing to distribute to your new subscribers. Remember that Coupon Carrier can’t generate the codes, you need to provide them.

How you generate a list of discount codes in your store depends on which platform you’re using. Contact the support of your E-Commerce platform to get help with that. Once you have a list of codes you can open the Add Codes tab and choose to import a file (.csv) or paste your codes. If you’re going to paste the codes then make sure that you only have one discount code per line and nothing else on each line.

For each code you import you need one credit. Each account codes with 25 credits for testing purposes. If you need to add more credits you can do so by clicking the Buy more credits button to the right. Add codes

Test the integration to make sure that everything works

The best way to test everything is to login to your MailChimp account and go to the lists section and find the list that you chose to monitor. Select Add subscriber from the list menu. Add subscriber menu

Enter the email address in the field that you’d like to use. Make sure that you haven’t used this email address for Coupon Carrier testing before since it keeps track of which email addresses have received codes. If a code have been assigned to an email address previously then it will be skipped and nothing will happen. This is to prevent misuse.

Add subscriber

A few moments later you should receive an email in your inbox, make sure that you check your spam folder in case it doesn’t arrive.

The message, logotype and button can all be changed in the configuration.
