Ecommerce Sign-Up Forms
Ecommerce Sign-Up Forms That Turn More Traffic Into Better Subscribers
Magicianly designs, builds and optimizes ecommerce sign-up forms and popup experiences in Klaviyo, Omnisend and Alia.
We focus on more than collecting email addresses. The goal is to capture better subscribers, learn more about them and improve what happens after signup.

The Common Problem
Most Ecommerce Popups Are Built Once and Forgotten
A generic 10% off popup might collect emails, but that does not mean the sign-up experience is working as hard as it could.
Performance depends on the offer, design, timing, device, targeting, questions, number of steps and what happens after someone subscribes.
Generic Popup
- Same experience for everyone
- Generic offer
- Weak trigger logic
- No useful customer data
- Rarely tested
- Optimized only for submit rate
Actively Managed Sign-Up Forms
- Intentional offer strategy
- Tailored visitor experience
- Smarter timing and targeting
- Useful zero-party data
- Ongoing A/B testing
- Connected to email automations
Sign-Up Form Strategy
More Than a Popup Design
One popup is not a list growth strategy.
Offer & Copy
What the visitor gets, how it is framed and whether it fits the product and margin.
Design
On-brand forms that read clearly on mobile and desktop without fighting the store.
Triggers & Targeting
Who sees which form, on which page, at which moment, and how often.
Zero-Party Data
Questions that tell you something useful about the person who just subscribed.
A/B Testing
Structured tests on offer, layout, steps and timing instead of one-off redesigns.
Lifecycle Integration
Every signup lands in the right segment and the right welcome path.
Popup Examples
Different Sign-Up Forms Solve Different Jobs
The right pattern depends on the traffic, the offer and the device. These are the sign-up form styles we build and test most often for ecommerce brands.
10% Off Your First Order
Your welcome offer, sent straight to your inbox.
Standard Popup
The workhorse. One clear benefit, one field, one decision.

Plus early access to new drops.

Zero-Party Data Popup

Zero-Party Data
A Better Sign-Up Form Can Tell You Who Just Joined Your List
The email address is only one piece of useful information.
A well-designed multi-step popup can also capture context that makes future marketing more relevant.

A Gift

Gift Buyer segment
Gift-focused welcome series
The question should earn its place. We only collect data that can actually change what the customer receives next.
Form Platforms
Use the Tool That Fits the Customer Journey
Klaviyo and Omnisend are strong native choices. Alia is an advanced option when the upside justifies a richer onsite experience.
Native ESP Option
Klaviyo Sign-Up Forms
A strong native choice for brands already using Klaviyo. Forms connect directly to profiles, segments and automations and are often enough for straightforward list-growth programs.
Best For
Brands that want native popup and email management in one ecosystem.
Native ESP Option
Omnisend Sign-Up Forms
A practical native option for brands already running their email marketing in Omnisend and wanting onsite capture connected directly to existing audiences and automations.
Best For
Brands already committed to Omnisend.
Advanced Option
Alia Popups
Best for brands that want more advanced popup experiences, stronger targeting, richer zero-party data and more sophisticated optimization.
Best For
Pushing popup performance beyond standard ESP forms.

Why We Sometimes Use Alia
For brands with enough traffic and upside, Alia can give us more ways to increase signup rate while also collecting richer subscriber data than a standard ESP popup.
Smart Triggering
Helps determine when a visitor is more likely to engage instead of relying only on fixed popup timing.
Prism AI
Can adapt popup content, offers and creative based on visitor context.
Zero-Party Data
Makes multi-step preference capture easier without presenting a large form all at once.
Smart Testing
Can continuously test and improve popup experiences across relevant ecommerce outcomes.
According to Alia, brands on the platform average 10%+ submit rates across thousands of stores, with multiple published case studies showing significant signup-rate improvements.
If the wider platform needs ownership rather than just the forms, that sits inside our retention marketing and Klaviyo management services.
Proof
What Better Sign-Up Forms Unlock
When the sign-up experience improves, the whole email program has more of the right people to work with.
More subscribers is the easy part. Better subscribers is the work.
We judge a sign-up form on the customers it produces, not only the addresses it collects.

Magicianly stands out above the rest
Emiel and his team are the only ones we've worked with who we fully trust to nail our messaging, understand our audience, and create the kind of graphics that align with our brand.

FAQ
Questions About Ecommerce Sign-Up Forms?
Straight answers on popup forms, list growth and the platforms behind them.
View All FAQsWhat is an ecommerce sign-up form?
An ecommerce sign-up form is any onsite opt-in that invites a visitor to join your email or SMS list. It can be a popup form, an embedded footer form, a full-screen sign-up form or a mobile slide-up.
Its job is not only to collect an email address. A good sign-up form sets expectations, captures context about the subscriber and hands that person to the right welcome path.
What is the difference between a sign-up form and a popup form?
A popup form is one type of sign-up form. It appears over the page based on a trigger such as time on page, scroll depth or exit intent.
Other sign-up forms are always visible, like an embedded form in the footer or on a landing page. Most brands need both: popups for new traffic and embedded forms for visitors who look for the option themselves.
What is a good popup conversion rate for ecommerce?
Many ecommerce brands sit somewhere between 2% and 6% of visitors who see the form, and well-optimized sign-up forms often perform meaningfully above that.
The number depends heavily on traffic source, offer, device and how the form is triggered, so we treat your own baseline as the benchmark and improve against it rather than chasing a generic figure.
Do sign-up forms work inside Klaviyo?
Yes. Klaviyo sign-up forms cover popups, flyouts, embedded forms and full-screen layouts, with targeting rules and multi-step options built in.
Because Klaviyo popup forms write directly to lists, properties and segments, the data captured at signup can immediately shape the flows and campaigns that follow.
Do you build sign-up forms in Omnisend?
Yes. Omnisend sign-up forms work the same way in principle: forms feed the audiences and automations already running in the account.
If your email program lives in Omnisend, we build and optimize there rather than pushing you toward a platform migration you do not need.
What are Alia popups?
Alia is a dedicated popup platform for ecommerce brands that want more advanced targeting, testing, personalization and zero-party data capabilities than a standard ESP form may provide.
Alia sign-up forms include intelligent triggering, multi-step experiences, visitor-specific personalization and advanced testing, and the collected attributes still sync into your email platform so they can drive segmentation and automations.
When should a brand use Alia instead of Klaviyo sign-up forms?
Klaviyo sign-up forms are often a strong choice when a brand wants a simple native setup inside the ESP, with popup forms, segments and flows in one place.
Alia can make more sense when the brand wants to push signup conversion further with more advanced targeting, dynamic experiences, easier zero-party data capture and automated testing.
The choice depends on traffic volume, existing performance, complexity and how much upside there is in onsite conversion.
What is zero-party data in a popup form?
Zero-party data is information the customer gives you deliberately, such as the category they shop, whether they are buying for themselves or as a gift, or the goal behind the purchase.
Collected inside a multi-step popup form, that context lets you segment on day one and send a more relevant welcome series, which usually matters more for list growth quality than one extra percentage point of submit rate.
