Key takeaways
- Shopify has a built-in email capture popup in Online Store → Preferences → Email marketing. It’s basic but works.
- For more control (timing, targeting, design, discount codes), use your email platform’s popup builder — Klaviyo, Omnisend, and Mailchimp all include one.
- The best popups: appear after 5-10 seconds or on exit intent, offer a real incentive (10-15% discount), and are easy to dismiss.
- Badly timed, undismissable popups hurt conversion rates. Restraint is a feature.
A well-designed email popup can capture 2-5% of your store’s visitors as email subscribers. Those subscribers become a high-value, owned audience — unlike social media followers or ad traffic, your email list is yours regardless of platform changes.
The challenge is deploying a popup that captures emails without frustrating shoppers into leaving.
How do I add an email popup on Shopify?
Method 1 — Shopify’s built-in email capture popup
Shopify includes a basic popup form natively.
Setup:
- Go to Online Store → Preferences
- Scroll to “Email marketing”
- Toggle on “Show a newsletter sign-up popup”
- Save
This popup:
- Shows after a brief delay on first visit
- Respects users who have already subscribed (doesn’t show again)
- Captures email addresses into Shopify’s customer list
- Has limited design customization
It’s the fastest way to get a popup live, but offers no targeting options, no exit intent, no A/B testing, and basic design.
Method 2 — Email marketing app popup builders (recommended)
Your email platform almost certainly includes a popup builder. These are significantly more capable than Shopify’s native option:
Klaviyo — if you’re using Klaviyo (the most popular Shopify email platform), its Signup Forms section includes a popup builder with:
- Timing controls (show after X seconds, on exit intent, after X% scroll)
- Page targeting (show on all pages, exclude cart page, target specific URLs)
- Segmentation (show only to new visitors, only to non-subscribers)
- A/B testing
- Discount code delivery
- Full design editor
Setup: In Klaviyo → Sign-up Forms → Create Form → choose Popup → design and configure → publish. Enable the Klaviyo App Embed in the Shopify Theme Editor.
Omnisend — similar popup capabilities to Klaviyo, with a slightly simpler interface. Good for stores earlier in their email marketing journey.
Mailchimp — basic popup support, works for stores that haven’t moved to a more advanced platform.
How do I set an email to pop-up?
“Email popup” refers to the signup form that captures visitor emails. The actual email delivery to the subscriber happens via your email platform (Klaviyo, Omnisend, etc.) — the popup is just the capture mechanism.
The connection: popup form → subscriber added to your email platform → welcome email sent automatically (via a flow or automation you’ve set up in your email platform).
What makes a good Shopify email popup
Timing
Too early (0-2 seconds): The visitor hasn’t even seen your products. There’s no reason to subscribe yet.
Recommended (5-10 seconds or on exit intent): Enough time to form an opinion about the store, not so long that committed buyers have already added to cart.
Exit intent: Triggers when the visitor moves their cursor toward the browser’s address bar or back button. This is the last moment you can intercept them without interrupting their browse — statistically one of the best-performing trigger options.
The offer
“Subscribe to our newsletter” converts at around 1% or less. A real incentive converts at 4-6%:
- 10-15% off the first order — the most common and effective offer for product stores
- Free shipping — effective if your baseline shipping cost is $5+
- Early access — works for new product launches or waitlists
- Free gift with first order — effective for stores with low-cost add-on products
Dismissability
A popup that can’t be easily closed infuriates visitors and drives them away. Always include a clear X button and a visible “No thanks” link. Making a popup hard to close does not increase signups — it increases bounces.
Frequency capping
Don’t show the popup to the same visitor every time they visit. Set a suppression window: once dismissed, don’t show again for 30-60 days.
GDPR and email capture
If you sell to EU customers, email capture must comply with GDPR. Key requirements:
- Clear consent language (“By subscribing, you agree to receive marketing emails from YourStore”)
- An explicit opt-in checkbox (pre-checked boxes are not compliant)
- A privacy policy link
- Easy unsubscribe mechanism
Most email platform popup builders include a compliant opt-in checkbox option. Enable it if you have EU traffic.
A/B testing your popup
Klaviyo, Omnisend, and most mature email platforms include A/B testing for popups. Test one variable at a time:
- Headline (“10% off your first order” vs. “Join 50,000 happy customers”)
- Timing (5 seconds vs. exit intent)
- Offer type (discount % vs. free shipping)
- Design (dark overlay vs. slide-in)
Run tests for at least 2 weeks before deciding on a winner. Email popup conversion rates vary significantly by traffic source — make sure your test has enough volume to be statistically meaningful.
