Are fullscreen popups actually back, or are we just rebranding intrusive popups with better UX?

I’ve been noticing more ecommerce brands testing full-screen pop-ups again, especially for welcome offers, list growth, and quiz-style entry flows.

A few years ago, fullscreen overlays felt like the “too aggressive” format:

  • bad on mobile
  • annoying if shown too early
  • risky for brand perception
  • easy to associate with low-quality discount tactics

But now they seem to be coming back in a different form.

What I’m seeing more often is not just a fullscreen email capture, but a fullscreen choice-based flow:

  • “What are you shopping for?”
  • “Men / Women / Gifts”
  • “Show me new arrivals / bestsellers / sale”
  • sometimes email comes only after that first choice

So I’m curious how people here see it:

Do fullscreen popups work better now because the format itself is stronger, or because marketers got smarter about what to put inside them?

My current theory is:

  • fullscreen still wins attention better than a standard lightbox
  • but it only works when it feels like a guided step, not a wall
  • the “choices” part matters because it makes the popup feel more like navigation/personalization and less like interruption
  • in other words, the format came back because the experience changed

I’m also wondering whether this is partly a response to the limits of classic discount popups.

A basic “10% off for email” popup can grow a list, but it can also:

  • attract low-intent signups
  • train people to wait for coupons
  • hurt brand feel if it appears too aggressively

A fullscreen popup with choices seems like a different bet:
capture less random demand, get a better signal, and maybe make the ask feel more relevant.

Curious what you’ve actually seen in practice:

  • Are fullscreen popups a good idea in 2026?
  • When do they outperform regular lightboxes?
  • Do choice-based popups improve conversion quality, or just make marketers feel better about being intrusive?
  • And where’s the line between “immersive” and “annoying”?

My take: fullscreen works only if it earns the interruption.

For me, it makes sense when:

  • there’s clear context
  • the first step gives value or direction
  • it’s shown with discipline, not instantly and not to everyone

So I don’t think fullscreen is “back” just because the format is strong.

It’s back because some brands now use it less like a wall and more like a short guided flow.

If it’s just a bigger version of a bad discount popup, it’s still bad.

Hi @Taras_claspo

Think we are gonna get along great :slight_smile: You talk about popups, and I talk about notifications as an alternative, as we did make an app for that.

I do not like pop-ups in general, but some are useful and do convert. Think most annoying ones are bad-timed popups. So, for example, I am a new visitor looking to browse the store for two seconds and then, boom, full scren popup. It does not matter if it is dicount, “Get 10% off if you subscribe to the newsletter,” or on the first order. It does not matter; I did not get a chance to see your store, and you are pushy about something.
Think, even if that converts some, it annoys a lot more who just leave the site.

So yes, your point " it’s shown with discipline, not instantly and not to everyone" is a correct one for me. For “the first step gives value or direction.” I’m not sure that should be in a popup. If it is the homepage, that should give enough directions. If it is a product page, no pop-ups should be needed to disctract customer. For “there’s clear context,” yes in several cases when you need to inform customers as a first action.

And your point from the first post: a full-screen choice-based flow that sounds like a quiz, and that is a valid tactic. Again, not for everyone. But is it a separate page or a full page popup, not sure of the difference. Besides that popup can run on any landing page.

Then why are notifications an alternative? Your phone doesn’t show every notification as a full-screen pop-up. It puts them in a feed you check when you’re ready.
The customer controls the interaction:

• They see a subtle indicator (like a bell icon with a badge)
• They choose to open it
• They browse offers, upsells, or updates in a clean, native-feeling interface
• They close it and keep shopping. No friction, no interruption

Maybe it is for differnt kind of customers, but still, it is not forced, no screen blocking. And it can work in conjunction with some popups.

Yeah quite agree on the point that it still works well if it eases the buy journey, adds value to shopping experience. If it appears to be an obstacle, it can cause irritation

Keep the popup if it is already capturing. Fullscreen vs lightbox is a timing question more than a format question.

What a lot of stores skip: a second, shopper-opened channel for people who already hit X. A bell does a different job than the first-visit overlay. New traffic still sees the popup. Returning people still have a place to grab the offer or join email/SMS.

I would not rip Privy/Klaviyo out the same week you test a bell. Run both. Public example: triquetrahealth.com still has a popup and uses a storefront bell.

Disclosure: I work on Atomato (Atomato Email, SMS & Upsell - Grow email and SMS lists and upsell from a feed... | Shopify App Store). The bigger lever this afternoon is still unknowns-only on the popup, plus a non-modal path for everyone else.
