Distributing unique coupon codes to visitors and customers on your website

So. You’ve generated a bunch of unique codes and now you want to distribute them to your customers and website visitors. Here’s how you do it:

Step 1: Sign up for Triggerbee
Step 2: Create a new coupon set and upload your CSV with your unique coupon codes.
Step 3: Create a new campaign. In the editor, add the single-use coupon code block. Select your coupon set in the block settings.
Step 4: Add your targeting rules and publish it on your website.

Why use unique coupon codes?

Using unique coupon codes is smart because it helps in a few important ways. First off, unique codes make sure that each customer gets their own special discount. It can add both an element of exclusivity and urgency to your marketing, increasing the chances of someone making a purchase.

Secondly, unique codes add a layer of security. Imagine you have a secret password to enter a club. In the same way, unique codes act as a special ticket, making it harder for someone to misuse or copy the discount.

Unique coupon codes also help you keep track of things. Multiple unique coupon codes are usually called “coupon sets” which lets ecommerce platforms and promotion platforms like Triggerbee manage them in a better way.

For example, let’s say you’ve uploaded 1 000 codes in a coupon set in Triggerbee. When customers start redeeming their coupons, you can easily see how many codes you have left in your set.

When to use unique coupon codes?

Unique coupon codes can be used for any promotion where you need an extra layer of security (to prevent code sharing or abuse), or when you want to create a sense of exclusivity. 

Here are some examples of promotions where you can use unique coupon codes:

• Referral campaigns
• Personalized promotions
• Individual loyalty offers
• As a reward after completing a survey
• In raffles and competitions
• For new registered members
• In re-engagement / winback campaigns
• Cart abandonment emails
• Welcome discounts

Unique coupon codes can be used any time you need to distribute a discount code, but you generally want to keep them isolated to specific campaigns. You generally want to avoid using unique coupon codes for site wide sales, clearances, and during larger holiday sales like Black Friday. During these circumstances it’s better to use a short static coupon code that is easy to remember.  

Unique vs static coupon codes

Coupon/discount codes come in two main types and both have pros and cons.

Unique coupon codes

Main benefit: Security and usage limitations (one code applies to one purchase).

• Made up of random letters and/or numbers.
• Offers high security due to a vast number of possible combinations.
• Typically unique and often single-use.
• Are challenging to remember, requiring customers to copy and paste during checkout.

Static coupon codes

Main benefit: Easy to remember.

• Utilizes a word or phrase, often tied to a promotion (e.g., “Spring15”).
• Easier for customers to remember compared to unique codes.
• Convenient for campaigns with multiple discount offers.
• Can be vulnerable to “coupon hacking.”
• It’s important to remember to set expiration dates to prevent abuse, even if codes are reused from previous campaigns.

Unique codes provide high security but can be hard to remember. Static codes are more memorable but require careful selection and usage limitations to avoid exploitation.

Best practices for static coupon codes

If you’re running a sale with different discounts (like 15% or 40% off), make sure to use unique codes for each offer. Most brands just add numbers to a keyword, like SEASON15 or SEASON40, which can cause problems.

Use different codes for each offer

Using the same pattern makes it easy for savvy shoppers to guess and grab the biggest discount. This is a common “coupon hacking” trick, but you can avoid it by using different codes for each offer.

Always add expiration dates

There are a bunch of coupon/deal sites that are known for keeping expired coupon codes for YEARS.

This can cause lots of people to use coupons even after the sale is over. While expired coupons are not redeemable, it’s not a critical business issue. However, users might feel “robbed” of a discount. Sometimes a customer just need a tiny discount as a nudge to get them to make the purchase.

It’s okay to reuse codes, but it’s important not to let them work all year. Be clear with customers about the expiration date, but don’t think they won’t try to use a discount you gave them a while ago – they will.

Magento allows you to create discount codes in bulk using two methods.

If you want to import a large amount of custom coupons at once you can upload them using a text (.txt) file in the Bulk Import Coupon Codes section.

In order to import a text file, make sure that your coupons are entered in a list format with one coupon per line.

Click the ‘Choose File’ button to select the text file and then ‘Import File’ to start the upload.

After the coupons are successfully imported a confirmation message will appear at the top of the Bulk import Coupon Codes section.

2. Paste coupon codes

If you only need to import a limited amount of custom coupons, you could simply enter them in the text area of the Import Coupon Code List section, or copy-paste them from another source like this coupon code generator.

Make sure you enter or paste the coupons using a list format with one coupon per line and click the ‘Import Coupons’ button to upload them.

After the coupon codes are successfully imported a confirmation message will appear at the top of the Import Coupon Code List section.
