Ask Shopify Sidekick whether your discount codes are working

Updated 15 September 2026 · SegmentIQ team at Marvel Labs

SegmentIQ adds its discount data to Shopify Sidekick. Ask "Was LOYAL20 worth it?" in your Shopify admin, and Sidekick answers with how much of the code's discount went to customers who had recently paid full price. It works on every plan, and you don't need to open the app.

What Sidekick can't see on its own

Sidekick can already report discount spend and redemptions from your store analytics. What those reports can't tell it is whether a discounted customer had recently paid full price, which is the sign that a discount went to someone who might have bought anyway. SegmentIQ calculates that from your order history and gives the figure to Sidekick when you ask about discounts.

Questions you can ask

• "Was LOYAL20 worth it?"
• "How much of WELCOME10 went to customers who had already paid full price?"
• "Which discount codes waste the most discount spend?"
• "Which customer segments get the most discount spend?"
• "Are our discounts worth it?"

You don't have to say "SegmentIQ". Sidekick picks the right source from what you ask. If it answers from Shopify's own reports instead, ask again and start with "Using SegmentIQ".

What the answer includes

An answer might look like this (illustrative numbers, and Sidekick words its answers its own way):

LOYAL20, last 180 days: 42 redemptions and $610 in discounts.
$390 of that (64%) went to customers who had paid full price
in the previous 180 days. 5% of redemptions were first-time buyers.
Estimate: a discounted order counts when the same customer paid
full price in the previous 180 days.

Every answer includes that method sentence, and SegmentIQ asks Sidekick to present a high share as a sign worth testing, not as proof the discount was wasted. Here's exactly how the figures are calculated.

How to start

1. Install SegmentIQ from the Shopify App Store and let the first sync finish. Until it does, Sidekick tells you the analysis isn't ready yet.
2. Open Sidekick from the top of your Shopify admin and ask a discount question.
3. The first time, Sidekick asks for permission to use SegmentIQ. Choose Yes, or Yes, and don't ask again.

From answer to action

On Pro, the discount report's What to change section suggests specific changes, each with a Copy Sidekick prompt button. For example:

• "Create a customer segment of customers who have not placed an order in the last 180 days, and limit the discount code LOYAL20 to that segment."
• "Limit the discount code INFLUENCER30 to the customer segment it was created for, and set a usage limit of one per customer."

Paste the prompt into Sidekick and it drafts the change in your admin for you to review. SegmentIQ itself stays read-only: its Sidekick tools only read figures, and nothing changes until you save.

Tips for better answers

• Start a new conversation for each new question. Sidekick carries context from earlier in the same conversation.
• Type the code exactly as customers enter it, for example LOYAL20.
• Ask about one code at a time for the full breakdown, or ask about your discounts in general for the top five codes and segments.

Questions

Which SegmentIQ plans work with Shopify Sidekick?

Every plan. On the free plan Sidekick's answers cover the last 90 days of orders; on Pro they cover the last 180 days.

Can Sidekick change my store through SegmentIQ?

No. SegmentIQ's Sidekick tools only read figures from SegmentIQ. If you ask Sidekick to change a discount, that's Sidekick working in your admin, and you review the change before saving it.

What does Sidekick receive from SegmentIQ?

Totals per discount code and per customer segment, such as redemptions, discount spend and shares, plus a sentence stating the method and date range. It doesn't receive customer names, emails or individual orders.
