Hi @Lorena Jaqueline,
 

Klaviyo does not automatically consider a coupon as "expired" if it has been used. In the absence of an expiration date, a coupon can be used multiple times until it is manually deactivated.

If you send another email in a flow to people who have already used their coupon, Klaviyo will generate a new coupon code for them, regardless of whether they have already used the original code or not. To avoid this, you can use a custom property to track whether a coupon has been used and use a segmentation condition to only send the reminder email to people who have not used their coupon.

Hi @Irrra ! 

Thanks for adressing my question! About this 

In the absence of an expiration date, a coupon can be used multiple times until it is manually deactivated.

This apply even if I set the coupon to be used only 1 time per customer?

you can use a custom property to track whether a coupon has been used and use a segmentation condition to only send the reminder email to people who have not used their coupon.

Would it be possible to give more info on how to do this? I feel lost since they’re dynamic coupons generated by Klaviyo. 

@Lorena Jaqueline 
 

Yes, I can certainly provide more information on how to do this with Klaviyo dynamic coupons!

Here is how you can use custom properties to track whether a coupon has been used and send the reminder email only to people who have not used their coupon:

First, you will need to create a custom property in Klaviyo to track whether a coupon has been used or not. You can do this by going to your Klaviyo account, then selecting "Profile and Fields" under the "Settings" menu.

Next, you will need to update the custom property when a coupon is used. You can do this using Klaviyo's API by sending a request to update the custom property when a coupon code is redeemed.

Now, you can create a segment in Klaviyo that includes only those people who have not used their coupon. To do this, you will use the custom property you created in step 1 as a segmentation condition.

Finally, you can use the segment you created in step 3 as the target audience for your reminder email.

Yes, this applies even if you set the coupon to be used only one time per customer in Klaviyo. In the absence of an expiration date, a coupon can be used multiple times until it is manually deactivated.

 If you need more specific help or have any questions, feel free to ask!

Thank you so much! I’ll try this way and come back if I have more questions, I really appreciate your help.

Hi @Irrra thank you for your help regarding dynamic coupons. I’m working on something very similar, but I can’t find the "Profile and Fields" section in Klaviyo, can you help me maybe with a screen shot of where it is located, thank you.
