TL;DR: A two-step popup asks a simple yes/no question first, then shows the email field after the visitor clicks. A teaser is a small tab that lets people reopen a popup they closed. Both cut friction and grow your list. In Klaviyo you build them as multi-step forms with a teaser attached. Two-step formats convert about 12% better than one-step popups, and teasers keep you clear of Google's mobile penalty.
A two-step popup in Klaviyo is a sign-up form that asks a simple yes/no question first, then reveals the email field only after the visitor clicks, and it lifts signups for Shopify brands by around 12% over a standard one-step popup. Most stores still run a single popup that demands an email the second someone lands. That feels pushy, and it leaves signups on the table. Two-step and teaser popups fix that by lowering the ask. The first click is easy. The email comes next, once the visitor has already said yes to something small. Across the Shopify stores we manage at CartStrings, the forms that open with a question or a teaser almost always beat the plain "enter your email" box. This guide covers what two-step and teaser popups are, why they convert, and exactly how to build them in Klaviyo without hurting your mobile SEO.
What is a two-step popup?
A two-step popup splits the sign-up into two screens. The first screen asks a low-friction question or shows an offer, like "Want 15% off your first order?" with a yes button. Only after the visitor clicks yes does the email field appear. Nothing personal is asked up front.
This is why people also call them micro-commitment popups. The first click is a tiny commitment. Once someone takes it, they're far more likely to finish, because people like to act in line with what they've already done. It's the same reason a "yes" at the door leads to a "yes" on the form. The offer sets the hook. The click builds momentum. The email feels like the natural next step instead of a cold demand. Compare that to a one-step popup, which shoves an empty email field in your face before you've even seen the product. One asks permission. The other just takes.
Teaser vs two-step popup
A teaser is a small tab that stays in the corner of the screen after someone closes your popup. A two-step popup is a full form split across two screens. They solve different problems, and the best Shopify stores run both together.
The teaser is your safety net. When a visitor dismisses your popup, the offer doesn't vanish. A small "Get 15% off" tab sits in the corner so they can reopen it whenever they're ready. That recovers signups you'd otherwise lose, without shoving the full popup back in their face. The two-step form is your conversion engine. It lowers the barrier to start. One gives control back to the visitor; the other pulls them in. Used together in Klaviyo, they capture the people who say yes right away and the ones who need a minute to look around first. Neither replaces the other. A store running a two-step form with no teaser is still losing every visitor who closes the box on reflex.
Do two-step popups convert?
Yes. Wisepops data shows multi-step popups, which include two-step formats, convert at 5.17% on average versus 4.62% for single-step popups, about 12% higher. Ecommerce email popups as a whole tend to land between 5% and 8%.
The lift comes from friction, not magic. A one-step popup asks for an email the instant someone arrives, and most people bounce. A two-step popup asks for a click first, which almost anyone will give. One large study of 1.8 million visitor sessions found micro-commitment formats drove up to eight to nine times more interactions and doubled signups compared with single-step popups, with no rise in bounce rate. Real brands see it too. Emma Sleep added a single "what are you shopping for?" step before its email form and lifted subscriptions by 50% over the one-step version. The extra step didn't slow people down. It pulled more of them in. Around 17% of Shopify stores now run multi-step popups, up sharply from a few years ago when they were rare.
Build it in Klaviyo
You build two-step and teaser popups in Klaviyo as multi-step forms. Head to the Sign-up forms tab, then either pick a multi-step template from the form library or start a blank form and add steps yourself. Klaviyo's guide confirms any form type works: popup, flyout, or full page.
Here's the build, step by step:
- Create the form. In the Sign-up forms tab, start a new popup or open a multi-step template.
- Design step one. Keep it to the question or offer and a single button. No email field yet. Fewer fields means less overwhelm and more first clicks.
- Add step two. Click the (+) Step button in the menu bar and choose the step type. Use a Blank Step or Profile Information block for the email, then a later step for SMS if you want phone numbers.
- Collect email first, phone second. Klaviyo recommends putting email on the first capture step and SMS on a later one, since mixing them on one screen slows email list growth. Use two separate lists so you can track each channel.
- Add a teaser. Click Teaser in the menu bar and set the size to Small, Medium, Large, or Custom. This is the tab that lets visitors reopen the form after they close it.
- Publish and watch the steps. You can add up to four steps plus a success message, and Klaviyo shows engagement per step so you can see exactly where people drop off.
That per-step data is gold. It tells you whether your offer is weak, which shows up as few first clicks, or your ask is too heavy, which shows up as drop-off at the email or phone step. Fix the step that's leaking, not the whole form.
When to trigger a popup
Don't fire your popup the second someone lands. Give it a short delay, trigger it on scroll, or use exit intent so it shows when a visitor is about to leave. Klaviyo's data shows exit popups beat plain landing popups by roughly 5%.
Timing is a lever most stores never test. Try an 8-second delay against a 15-second delay, then against scroll depth and exit intent, and let the numbers pick the winner. Your offer matters just as much. For ecommerce, the offers that pull best are a 10% to 20% discount on the first order, free shipping when shipping cost is a known blocker, or a free gift with the first order. Keep the form to one or two fields, match your brand's colors and fonts so it feels built-in, and suppress people who already signed up so you're not nagging subscribers. If you want this dialed in across your whole capture setup, that's exactly what our popup and capture setup handles.
Popups and mobile SEO
Teaser popups keep you on the right side of Google. On mobile, a full-screen popup that covers content the moment someone arrives can trip Google's intrusive interstitial penalty. A teaser is a small corner tab, so it doesn't block the page, and the full form only opens when the visitor taps it.
Because the tap is a user action, the popup counts as user-initiated and sidesteps the penalty. That's a big deal for Shopify stores that get most of their traffic on phones. The safe pattern on mobile is simple: lead with a small teaser or a bottom slide-in, not a full-screen takeover, and let the visitor open the form on their terms. You capture emails and protect your search rankings at the same time. Most Klaviyo popup guides skip this entirely, and it quietly costs stores traffic they never see leave.
Mistakes that lose signups
The biggest mistake is asking for too much, too soon. A popup that demands email and phone on one screen the instant someone lands will underperform every time. Split the ask, delay the trigger, and give people a reason to say yes.
A few more that hurt:
- No teaser. When someone closes your popup with no way to reopen it, that signup is gone for good.
- Same popup for everyone. Show returning subscribers the form again and you annoy your best customers. Suppress people who already converted.
- Weak or vague offer. "Sign up for our newsletter" doesn't move anyone. Name the reward.
- Never testing. Timing, offer, and copy all swing results, so test one at a time.
If you're not sure your forms are pulling their weight, a Klaviyo audit will show you where the leaks are. And the emails those popups collect only pay off if your welcome flow automations turn new subscribers into buyers.
Where two-step popups fit
Two-step and teaser popups aren't a gimmick. They're the difference between a list that grows slowly and one that grows on its own. The two-step form lowers the barrier so more visitors start. The teaser catches the ones who almost left. Built together in Klaviyo as a multi-step form, they can lift signups by double digits while keeping you clear of Google's mobile penalty.
Start simple: a question on step one, the email on step two, a teaser in the corner, and an exit trigger. Then watch the per-step data and tighten from there. If you'd rather have it built and tested for you, we do this every day for Shopify brands. Book a call and we'll map out a capture setup that actually fills your list. Want more tactics first?

Frequently Asked Questions
What is a teaser popup?
A teaser popup is a small tab that stays in a corner of your site after a visitor closes your main popup. It lets them reopen the offer whenever they're ready, so you recover signups you'd otherwise lose. Because it doesn't block the page, it also feels far less intrusive than a full popup.
Are two-step popups better?
Usually, yes. Two-step popups ask for a click before an email, which lowers friction and builds commitment. Klaviyo popup data and Wisepops both show multi-step formats convert around 12% higher than single-step popups on average, and some brands see much bigger lifts. Test both against your own traffic to confirm.
How many steps can I add?
In Klaviyo you can add up to four steps to a sign-up form, plus an optional success message. A common setup is a question or offer on step one, email capture on step two, and SMS on a later step. Klaviyo shows engagement per step so you can spot where visitors drop off.
Do popups hurt SEO?
They can, but they don't have to. On mobile, a full-screen popup that covers content on arrival can trigger Google's intrusive interstitial penalty. A teaser or bottom slide-in that opens only when tapped counts as user-initiated, so it avoids the penalty while still capturing emails.
What offer converts best?
For ecommerce, a 10% to 20% discount on the first order usually converts best. Free shipping works well when shipping cost is a known reason people don't buy, and a free gift with the first order is a strong alternative. Whatever you pick, name the reward clearly on step one.
