Welcome to the community @Priyanka10
As winback discounts are typically higher than you would normally offer, I’d recommend using a dynamic code that’s unique and single-use per customer. A static code could find it’s way into the wild!
I also suggest adding a prefix to those dynamic winback codes such as ‘MISS-YOU-’ or similar: this allows you to select/filter all those codes on the prefix should you need to in segments, flows etc
Regarding the expiry date, that’s a business decision. Typically I’ll go for between 7-days and 30-days after it’s sent which allows for a few emails in the winback flow to nudge anyone who’s not yet redeemed/purchased once they’re in the flow.
Hope that helps

Hey @Priyanka10 ,
I recommend using dynamic codes as static codes can be picked up by various coupon sites. As Bluesnapper said, I would also suggest a 30-day expiration date. This gives you the added ability to create a sense of urgency and having multiple emails in this winback (Only 2 days left to use your special discount…).
