Email capture: Best tools, forms, and tactics for ecommerce

According to Omnisend’s data, ecommerce merchants generated an ROI of $79 for every dollar spent on email marketing in 2025. To achieve similar returns, you need email capture, which means collecting visitors’ email addresses through signup forms, popups, landing pages, and incentives. 

This helps your ecommerce store turn visitors into subscribers you can market to many times. When you send relevant content and offers, these subscribers can convert into loyal customers who drive revenue for your store.  

In this guide, you’ll discover the best email capture tools to use, popup examples that increase signups, and seven proven best practices. You’ll also get simple form templates you can tweak for your campaigns.

What is email capture?

Email capture involves collecting email addresses from potential customers or website visitors with their clear permission.

You can do this using signup forms, popups, teasers, landing pages, or floating bars placed strategically on your website. Ecommerce brands also use lead magnets, such as discounts, free shipping, or early access, to give shoppers something valuable in return for their email address. 

Strategic email capture is an important part of learning how to build an email list. Once you have prospects’ email addresses, you can use them for marketing, sales, or other communications.

For ecommerce brands, email capture creates a direct marketing channel you fully own. Social platforms constantly change their algorithms, while paid ads now cost more. Email gives you a reliable way to reach shoppers without paying for every click.

Email capture vs. email harvesting

When it comes to email capture, shoppers willingly share their addresses via signup forms or popups. They decide to hear from your brand in exchange for something useful, like a discount, a free guide, or early access.  

Email harvesting, on the other hand,  involves collecting addresses from the web without consent. This is often done using scraping tools or purchased lists. That approach hurts email deliverability, damages trust, and can violate privacy laws like GDPR for ecommerce.

According to a Litmus 2026 study, GDPR fines can cost your brand up to 4% of its annual revenue. So, collecting proper consent during email capture is important to avoid these issues. 

Types of email capture forms

There are several kinds of email capture forms, including embedded forms, popups, landing pages, teasers, and floating bars. Each type works for different stages of the customer journey.

Here’s how each form works, and when to use it.

Popup / modal forms

Email capture popup forms temporarily appear over your store’s content and request shoppers to share their addresses. Most ecommerce brands like using them for welcome discounts, seasonal offers, and cart-saving incentives. For instance, a Shopify popup promising a 15% discount can help you convert first-time visitors into subscribers.

Popups convert well because they catch the visitor’s eye. However, displaying them too early can disrupt the browsing experience and annoy visitors. 

Embedded forms

Embedded forms sit directly inside website pages. You can place them in blog posts, footers, product pages, or checkout areas. 

They feel more natural and less disruptive than popups. This makes them suitable for newsletter signups, guides, or other educational content. However, they’re easier to miss. Your store visitors may scroll right past them without noticing.  

Floating bars

Also known as sticky bars, these email capture forms remain fixed at the top or bottom of the screen as shoppers browse. You can use them to promote flash sales, free shipping perks, or limited-time offers.

While floating bars don’t block content, you don’t get enough space for detailed copy and images. 

Landing pages (email capture page)

These are dedicated website pages designed solely for collecting subscriber information. Ecommerce brands often send paid traffic, social media visitors, or giveaway participants to these pages.

These pages don’t get casual store traffic, so you have to drive visitors to them through links or ads actively.

Teasers

Teasers are small tabs or icons that sit in the corner of the screen. They expand into a full email capture form when clicked. You can use them to promote discounts, VIP clubs, or early access campaigns.

Visitors get more control and fewer interruptions. Even so, teasers are less visible and easier to miss than full popups. 

Omnisend natively supports all five email capture form types. You can use its form builder to create and test various signup forms for your store.

Quick pick for ecommerce stores

If you run a small store or are just starting to grow your email list, Hello Bar or Popupsmart would be great options. Mid-sized ecommerce brands usually get the most value from Omnisend because it combines signup forms with email segmentation, automation, and ecommerce integrations on a single platform. 

Larger stores with dedicated marketing teams can use OptinMonster or Wisepops to run more targeted campaigns and optimize conversions. Still, if you want one balanced solution for stores of all sizes, Omnisend is a great pick.  

Email capture best practices for ecommerce

The most effective email capture best practices for ecommerce stores focus on strong value and strategic timing. Most brands fail because they either show forms too early or give shoppers no reason to subscribe.

The strategies below help you convert visitors into subscribers while offering a smooth shopping experience.

1. Use a lead magnet with a clear value exchange

Give shoppers a clear reason to share their email address. A simple “Join our newsletter” message rarely works anymore. The goal is to entice them with something valuable enough that they’re willing to part with their email. 

For ecommerce stores, the best lead magnets include:

• First-order discounts
• Free shipping
• Early product access
• Ebooks
• Limited-time deals

Island Olive Oil uses a simple popup created using Omnisend to drive email signups. The popup promises a 10% off discount for the first order:

The tactic works because the value is front and center. People feel more comfortable signing up when they know exactly what they’re getting. Omnisend’s study shows that popups with a discount had a 2.4% conversion rate, compared to 1.7% for those without a discount.

2. Time your forms correctly

Avoid showing your email capture form the second someone lands on your site. Let visitors browse first so they can build interest in your products. 

If your popup appears too quickly, shoppers may close it before reading anything. Too late, and they might leave without noticing it. The sweet spot, according to Omnisend, is six to 10 seconds, which gets a 2.4% conversion rate. 

Most ecommerce brands also trigger forms based on behavior:

• After scrolling 30–60% of a page (especially for long-form content)
• After viewing multiple products
• On exit intent (when a visitor moves their cursor towards the X button)
• After adding products to the cart

Here’s an example of an exit popup that Omnisend can show when a visitor is about to leave a website:

3. Segment by visitor type

Group your ecommerce store visitors based on their behavior and purchase history. This lets you show more relevant, personalized email capture forms and incentives to each segment. 

You can test these signup form examples for different types of shoppers:

• New store visitors: An attractive first-order discount, like 10% off, encourages signups and purchases 
• Returning shoppers: Offering loyalty rewards or early access to new items is a great way to win over dedicated customers 
• Cart abandoners: Buyers are likely to come back, sign up, and complete their orders when you offer free shipping 

This strategy improves conversions by offering shoppers deals that align with their stage in the buying journey. What’s more, audience segmentation helps you send targeted follow-up email marketing campaigns later.

Omnisend’s advanced targeting capability lets you create tailored segments for your email capture campaigns:

4. Keep forms short

Ask for as little information as possible in your ecommerce email capture forms. An email address is usually enough. Every extra box you ask someone to fill out, like their last name or phone number, makes them more likely to quit. 

A 2025 study by Omnisend found that simple forms with just one single box to fill out saw a 2.1% sign-up rate. On the flip side, forms requesting five or more details dropped to just 1.4%.  

Many successful email capture examples use a single-field form with one strong CTA. They increase conversions by reducing effort and speeding up sign-up.

Take Organic Aromas, for example. The brand used Omnisend to create this neat email capture popup, which achieved a 6.8% conversion rate. In just a week, it captured 135 new subscribers, and 10 of them made purchases. It includes a clear discount offer, one signup field, and a prominent CTA:

5. Optimize for mobile (and protect your SEO rankings)

According to Statista, mobile devices drove 57.27% of all website traffic in 2026. This means your email capture forms must work well on small screens. If your forms are hard to close or block the entire screen, shoppers will become frustrated and leave. 

Google also penalizes intrusive mobile popups that block content and hurt user experience. This may result in lower rankings, reduced visibility, and lower conversion rates. 

To improve mobile email capture performance:

• Use smaller popups like slide-ins and floating bars 
• Keep buttons large enough to tap
• Avoid covering important content
• Add clear close buttons
• Ensure your forms load quickly

Our mobile popup guide explains mobile-friendly design best practices in more detail. By implementing them, Vape Superstore achieved excellent results. After using Omnisend’s mobile-friendly, multi-step email and SMS capture forms, the brand’s mobile signup rate jumped from 18% to 32%. 

Omnisend offers an intuitive form builder that you can use to create mobile-optimized signup forms with minimal effort:

6. A/B test your popup copy and offer

Experiment with different headlines, offers, button text, images, and timing rules to see what your audience loves most. Even the tiniest tweaks in your wording can improve signup rates. 

For example, you might test:

• “Get 10% off” vs. “Unlock free shipping”
• “Join now” vs. “Claim my discount”
• Product-focused images vs. lifestyle photos

Consistent testing helps you refine your signup forms based on real shopper behavior instead of guesswork.

B-Wear Sportswear initially struggled to get significant results from its 10% email signup discount. After switching to Omnisend, the brand upgraded to a 20% discount and used the platform’s automation tools to optimize its welcome sequence. This resulted in a 66% conversion rate in just two months.  

7. Use exit-intent as a last-chance capture

Exit-intent popups appear when a visitor moves their cursor toward closing the tab or leaving your store. These forms give you one final chance to collect an email address before losing the shopper completely. 

Since the shopper already plans to leave, exit-intent email capture forms are less disruptive than instant popups. Many WooCommerce, BigCommerce, and Shopify store owners use exit-intent popups to recover visitors without interrupting browsing too early. 

Some effective last-chance offers you can consider include:

• Limited-time discounts
• Free shipping
• Bonus gifts
• Reminder offers
• Cart-saving incentives

Omnisend helped Organic Aromas drive a 150% increase in email signups with an exit-intent popup. The form included one signup field and a clear 10% discount on the first purchase.

Email capture popup examples

High-converting ecommerce popups usually combine a strong offer, mobile-friendly design, simple fields, and precise timing. They make the value obvious within seconds and focus on one clear action. 

Let’s discuss the most popular email capture popup examples you can use to drive signups and sales.

Welcome discount popup

A welcome discount popup appears when someone first visits your store. You can use it to offer a valuable incentive to visitors in exchange for their email addresses. 

According to a 2026 Wisepops report, email capture popups with discounts had a 7.45% conversion rate. This is 62% higher than the 4.6% conversion rate for those without discounts. 

Most welcome popups offer:

• 10% to 15% off
• Free shipping
• First-order bonuses

Once visitors sign up, you can choose welcome email templates to deliver the discount code.

This welcome email capture popup from Omnisend uses a 10% discount offer to encourage new visitors to sign up:

Exit-intent popup

You should use exit-intent popups when shoppers show signs of leaving your website. They help you catch the visitor’s attention one last time and reduce bounce rates. 

Wisepop’s 2025 data show that exit-intent popups had a 3.94% conversion rate in 2026. While lower than other popup types, they can help you recover 10% of abandoned visitors.

These campaigns work best with urgency-focused offers like:

• Limited-time discounts
• Free shipping
• Shopping cart offers and reminders

Here’s an exit-intent popup offering $10 off before visitors leave the store:

Spin-to-win / Wheel of Fortune popup

These popups turn email capture into a game. Instead of showing a standard discount form, shoppers spin a virtual wheel to win prizes. Since winning is exciting, visitors are more likely to enter their details.

Omnisend data reveal that Wheel of Fortune popups achieved a 3.5% conversion rate, compared to 2% for standard forms, in 2025.

Ecommerce brands use gamified popups to increase engagement and drive higher signup rates. They work well for holiday sales or product launches. 

Typical wheel prizes you can offer include:

• Percentage discounts
• Free shipping
• Bonus gifts
• Store credit

This spin-to-win popup from Omnisend offers percentage discounts in exchange for an email address:

SMS + email double opt-in popup

A double opt-in popup collects both an email address and a phone number. You can use this email capture method to grow your email and SMS marketing list. 

Start by asking for an email address first, then request a phone number on the next screen.  In fact, Omnisend statistics show that multi-step popups outperform standard ones. In 2025, multi-step forms had a 2.3% conversion rate, compared with 2% for single-step popups. 

The key is to offer stronger incentives. For example, this two-step popup from Omnisend offers a 10% discount for email capture and an additional 5% for a phone number: 

Teaser form

Teasers stay minimized until the shopper clicks them. You can use them to keep promotions visible without interrupting browsing or product discovery. They’re particularly effective for mobile because they take up very little screen space.

Wisepop’s 2026 data show that popups placed on the top-left side convert better (6.8%) than those on the top-right side (6.57%). 

Here’s an example of a teaser email capture form from Omnisend that offers 30% off on the first purchase: 

Email capture form templates

Email capture templates are ready-made popup and sign-up form layouts you can customize for your store. A great template should include a catchy headline, a clear benefit, and a CTA button that tells shoppers exactly what to do next.

You can paste these templates directly into your form builder and tweak offers and branding to match your store.
