Sending discount codes in your emails

You can now include the discount a visitor received from a popup directly in a Popup-connected email using a merge tag.

What it's for

A lot of popups generate a discount code for the visitor, either a fixed code from a standard coupon popup, or a code tied to whatever prize they land on in a spin-to-win wheel popup. Until now, that code only showed up inside the popup itself. If a visitor closed the popup before copying it, or just wanted it in their inbox, there was no easy way to follow up with the right code automatically.
The {{ discount_code }} merge tag solves that. Drop it into any Popup-connected email, and it's replaced with that specific visitor's code when the email sends.

The merge tag

{{ discount_code }}

Wherever you place this in your email content, it's swapped out for the real discount code belonging to the visitor who triggered the email.

Where it pulls the code from:

• Regular coupon popups - the fixed discount code set up on that campaign.
• Spin-to-win (wheel) popups - the specific code tied to the prize the visitor landed on, not just any code from the wheel.

Either way, you don't need to know in advance which code a visitor will get. The merge tag always resolves to the right one for that person.

Adding it to an email

1. Go to the Conversion tab of your popup campaign and open Send an Email.
2. Select an existing email or create a new one.
3. In the email editor, place your cursor where you want the code to appear.
4. Insert the merge tag: {{ discount_code }}
5. Save and send yourself a test email to confirm it resolves correctly.

Tips

• Make the code stand out. Bold it, put it on its own line, or box it visually, so it isn't lost in paragraph text.
• Don't hardcode a fallback code. If you type a specific code next to the merge tag "just in case", you risk sending two different codes in the same email, which confuses customers. Trust the tag.

Common questions

• What happens if the popup doesn't generate a code at all, like an announcement popup?
• • The merge tag has nothing to pull in that case, so avoid adding it to emails connected to campaigns that don't issue a code.
• Will this work for a campaign I've already published?
• • Yes. You can add the merge tag to any existing Popup-connected email; it applies going forward to new emails sent from that campaign.
• Does the code expire based on when the email is sent, or when the popup was shown?
• • The code itself follows whatever expiration rules you've set on the discount in Shopify. The merge tag only inserts the code, it doesn't change its expiration.
• Can I use this merge tag outside of Popup-connected emails?
• • No, it's only available in emails tied to a popup campaign, since that's where the code comes from.
