How to Grow Your Shopify Email List Without Relying on Popups
Popups are the default email capture method for Shopify stores. But they only convert 2-5% of visitors. Here are the methods that grow your list faster — including some that work on visitors who never interact with a popup at all.

TL;DR
- Standard email popups convert 2-5% of Shopify store visitors. This means 95-98% of your traffic leaves without joining your email list.
- Relying only on popups limits your list growth to a small fraction of your total traffic, regardless of how well-designed the popup is.
- Visitor identification tools like Attribuly Capture can match anonymous visitors to email addresses without requiring a form submission, growing your list from the 95% of visitors that popups miss.
- The fastest-growing Shopify stores combine multiple capture methods: optimized popups, checkout email capture, content-based forms, interactive tools, and visitor identification.
Why popups alone are not enough
Email popups are effective for the visitors who see them and engage. The problem is volume.
| Capture method | Typical conversion rate | Visitors it can reach |
|---|---|---|
| Email popup (discount offer) | 3-5% | All visitors who see the popup |
| Email popup (no discount) | 1-3% | All visitors who see the popup |
| Footer signup form | 0.5-1% | Visitors who scroll to bottom |
| Checkout email field | Varies | Visitors who reach checkout |
| Visitor identification (Capture) | 15-35% match rate | All visitors, including those who ignore popups |
The key difference is that popups and forms require the visitor to voluntarily submit their email. Visitor identification matches anonymous sessions to known email addresses using first-party data networks — no form submission required.
Seven methods to grow your Shopify email list
Method 1: Optimize your popup strategy (still important)
Before adding new capture methods, make sure your popup is performing at its best.
Popup optimization checklist:
- Timing: Show after 5-10 seconds or 50% scroll depth, not immediately on page load.
- Offer: A specific discount (10% off, free shipping) outperforms "join our newsletter" by 2-3×.
- Mobile design: Full-screen popups on mobile are penalized by Google. Use a bottom bar or slide-in instead.
- Exit intent: Trigger a second popup when the visitor moves to leave (desktop only).
- Frequency: Do not show to the same visitor more than once per session.
- A/B test: Test different offers, copy, and designs monthly.
Expected list growth: 3-5% of visitors who see the popup.
Method 2: Capture email at checkout earlier
Shopify's checkout flow includes an email field. When a shopper enters their email — even without completing the purchase — Klaviyo can identify them for the abandoned checkout flow.
How to optimize:
- Ensure the email field appears as the first step of checkout.
- Consider Shopify's one-page checkout (if available on your plan) which shows the email field immediately.
- Enable Shop Pay, which auto-fills customer information including email.
Expected impact: Captures email from shoppers who start checkout but abandon. This group has the highest purchase intent.
Method 3: Use interactive content that requires email
Instead of asking "enter your email for 10% off," give visitors a reason to share their email by providing value first.
Examples:
- Product quiz: "Find your perfect [product]" → requires email to see results.
- Size finder: "Get your recommended size" → email to save results.
- Assessment tool: "Test your [relevant metric]" → email to get score (Brand V in our case study used an online hearing assessment).
- Waitlist: "Get notified when [product] is back in stock" → requires email.
- Early access: "Be first to shop our new collection" → requires email.
Expected conversion: 10-25% of visitors who start the quiz or tool (much higher than passive popups because the visitor has already invested effort).
Method 4: Content-based email capture
Offer downloadable or gated content that your target audience values.
Examples for DTC brands:
- Buying guide ("The Complete Guide to Choosing [Product Category]")
- Comparison chart (your products vs competitors)
- Care instructions or usage tips
- Lookbook or styling guide
- Industry report or statistics
Placement: Embed these offers within relevant product pages or blog posts, not just in popups.
Method 5: Leverage post-purchase for list building
Existing customers are your best source of high-quality email contacts for future marketing.
Tactics:
- Review request emails: Ask for a review and confirm email opt-in for marketing.
- Referral program: "Share with a friend, both get [discount]" → captures friend's email.
- Warranty registration: For electronics or high-AOV products, offer extended warranty registration via email.
Method 6: Use social proof to drive signups
Show visitors that other people have already joined your email list.
Tactics:
- Display subscriber count: "Join 25,000+ shoppers who get early access"
- Show recent signup activity: "12 people signed up in the last hour"
- Include testimonials about your email content quality
Method 7: Add visitor identification (Capture)
This is the method that reaches the 95% of visitors who never interact with any popup or form.
How Capture works:
- A visitor browses your Shopify store — views products, adds to cart, or starts checkout.
- Attribuly's Capture matches the visitor session to a known email address using first-party identity data.
- The email is synced to Klaviyo, where the contact enters your existing flows (abandoned cart, browse abandonment, welcome series).
- The visitor receives relevant email follow-up without ever having submitted a form.
Why this matters for list growth:
- Popups depend on visitor action. Capture works passively on all qualifying visitors.
- Capture focuses on high-intent visitors (product viewers, cart adders, checkout starters) — the contacts most likely to convert.
- One DTC hearing aid brand (Brand V) grew their identified contact list by 20,221 in five months using Capture.
Expected impact: Capture typically identifies 15-35% of anonymous US visitors, which can grow your reachable email audience 3-10× compared to popups alone.
How these methods work together
The most effective approach is not choosing one method. It is layering all of them:
| Layer | Method | Visitors it reaches | Effort |
|---|---|---|---|
| 1 | Optimized popups | All visitors (3-5% convert) | Low |
| 2 | Checkout email capture | Checkout starters | Low |
| 3 | Interactive tools | Engaged visitors | Medium |
| 4 | Content-based capture | Blog/guide readers | Medium |
| 5 | Post-purchase / referral | Existing customers | Medium |
| 6 | Visitor identification (Capture) | All visitors (15-35% match) | Low (install + activate) |
Layers 1-5 capture visitors who voluntarily share their email. Layer 6 (Capture) reaches visitors who do not interact with any form — which is the vast majority.
Common mistakes in email list growth
Mistake 1: Measuring popup conversion rate instead of overall capture rate
A 5% popup conversion rate sounds good. But if only 60% of visitors see the popup, your actual capture rate is 3% of total traffic. Measure email capture as a percentage of total visitors, not popup viewers.
Mistake 2: Offering the same popup to every visitor
First-time visitors respond differently than returning visitors. New visitors may need a discount. Returning visitors may respond better to "early access" or "new arrivals." Segment your popup strategy.
Mistake 3: Ignoring mobile capture
Over 70% of Shopify traffic comes from mobile devices. If your popup is designed for desktop, you are missing most of your audience. Use mobile-specific formats (bottom bars, slide-ins) and test on multiple devices.
Mistake 4: Growing the list without growing the flows
A larger email list only generates more revenue if you have flows to activate those contacts. Before investing in list growth, ensure you have at least: abandoned cart flow, browse abandonment flow, welcome series, and post-purchase sequence in Klaviyo.
Next step
Start by measuring your current email capture rate: total new email contacts last month divided by total website visitors. If it is below 5%, visitor identification is the highest-leverage next step.
