DCBKlaviyo Welcome Codes During a Sale: Stop the 10% Off Stacking on Shopify
By Viktoriia Pavlova · · 5 min read
Quick answer
Welcome popups keep handing out unique codes during your sale, and shoppers stack them on sale prices. Keep the popup running for sign-ups, but use DCB to block those codes on sale items or for the whole sale window.
Why welcome codes hurt during sales
Klaviyo, Privy, Omnisend and similar tools generate a unique welcome code for each sign-up. During Black Friday your traffic spikes, so thousands of new codes go out — and each one stacks on your already-discounted prices.
Options you have
- Pause the popup — you lose sign-ups during your busiest week
- Change the offer to free shipping — requires editing flows and templates
- Keep the offer, restrict where it works — best of both
Restrict welcome codes with DCB
- Keep your Klaviyo flow as is.
- In DCB, choose block codes on compare-at price items so welcome codes only work on full-price products, or block all codes for the sale window.
- Update the popup text: “10% off full-price items”.
- Set a friendly checkout error message.
After the sale the schedule ends and welcome codes work everywhere again. For more on overlapping offers see how to stop discount stacking.
