Grow your email and SMS lists without interrupting shoppers

Asking for an email address is almost a given for any Shopify store. Usually that means a homepage popup that offers a discount in exchange for a signup, and that popup earns its place. The problem starts when the whole list-building strategy becomes "just add another overlay": a second popup for SMS, a floating newsletter bar, a spin-to-win on exit, a restock banner.

On desktop, that stack of overlays looks absurd. On mobile, it can cover the entire screen on first paint, so the shopper closes everything before reading a word.

There is another way to keep growing email and SMS lists: keep the popup that converts, then add a second path the shopper takes themselves. This article covers what that structure looks like, what to measure, and where the data has to go.

Start by auditing your current interruptions

Before adding anything, list everything that appears without the shopper asking for it: the email popup, any SMS request, cookie and consent notices, currency or region prompts, free-shipping bars, and app widgets you may have forgotten. Open your store on a phone, throttle the connection, and count how many things you dismiss before you can see a product. If it takes more than one tap, your list growth is limited by lost interest, not by the offer.

Keep the popup and tune it

Removing the popup is not the answer, because it is still your main source of signups. Tune it instead:

Trigger on intent, not on arrival. Fire it after a set scroll depth, a second page view, or a few seconds on a product page, so the shopper has seen something worth subscribing for.

Reduce frequency for returning visitors. People who have already dismissed the offer twice should not see it a third time, and neither should current subscribers. Longer suppression for repeat visitors costs few signups and removes a lot of irritation.

Exclude checkout and cart pages. Any overlay there competes directly with the transaction.

Ask one thing per step. A single field converts better than email and phone fields stacked together with two consent checkboxes.

Add an optional path the shopper chooses

The second path should be one the shopper chooses to open. That is how a notification feed works: a bell icon in the header that sits quietly, shows a count when something is new, and opens only when tapped. Because it does not cover the page, it can hold several messages at once without stacking overlays.

Useful things to put in that feed:

A signup card (NotiEmail and NotiSMS, on Enterprise+): ask for email first, then offer SMS as a follow-up step once the email is captured. Shoppers who opened the feed themselves are a warmer audience than those interrupted on arrival.

Triquetra Health runs this email-first, SMS-second capture inside its feed. The Triquetra case study shows it running alongside the store's existing email and SMS program.

Restock and back-in-stock notices, with the product image and a direct link.

Offers that are valid right now, plus the shipping minimum, which would otherwise need a second banner.

Subscription updates, such as the renewal date for signed-in SKIO subscribers (the SKIO integration is on Enterprise+), which give customers a reason to open the bell again.

Atomato is the app we build for this surface. It adds the bell and feed alongside your existing popup without removing it, and it handles on-site messages only. It does not send campaigns.

Send the data to the right place

Atomato is not an email or SMS platform. It does not send broadcasts, and it should not become your system of record. Everything captured on-site should sync straight into the tool you already send from, so segments and flows stay in one place. Atomato sends email signups to Klaviyo, Mailchimp, Omnisend or Drip, and phone numbers to Klaviyo, or to Mailchimp when the email step also uses Mailchimp. Attentive is coming soon.

One point worth clarifying, because it comes up often: SKIO is a subscriptions app, not an email destination. The SKIO integration is for subscription stores and is useful for targeting subscribers (for example, a card shown only to people with an active subscription), but subscriber email addresses should go to your ESP, not to SKIO.

Practical suggestions

Lead with intent. Use a Page URL rule to show the signup card on product or collection pages, where the shopper has already seen something worth subscribing for. The card waits in the feed until the shopper opens it.

Go multi-step: email first, then phone. Ask for the phone number on its own step after the email, with its own disclosure line, and accept that only some shoppers will give it.

Target by page and sign-in status. A signup card with a Cart value, Cart items, Cart products or Exit Intent rule never shows, so use Page URL, UTM or Device rules for signups. Shoppers who are not signed in can see the discount offer. Signed-in customers can see restocks or other updates instead.

Match the ask to the region. Where SMS consent rules are stricter, keep email as the default path and treat SMS as opt-in only.

Do not run the popup and the feed signup card on the same page at the same time. Make one the primary ask and leave the other available.

Measure honestly, by source and step: popup submissions, feed opens, feed signup submissions, and phone numbers added after email. Check unsubscribe rates and how often the popup was shown to people who were never a good fit. Those numbers tell you whether the second path is bringing in new subscribers or just moving signups from one surface to the other.

Be careful with conversion-rate claims. Attributing revenue to a signup surface is hard, and published "lift" figures usually say more about the store that reported them than about yours. Measure signups per session before and after, then check downstream flow performance in your ESP over a full sending cycle.

Where to start

Make one change this week: tune the popup by raising its trigger threshold and lengthening suppression for returning visitors. After that, add the feed as an alternative path and put a signup card in it. Sync signups to your ESP from day one so nothing is stranded on-site.

If you want to try the feed approach, Atomato is on the Shopify App Store, and you can find more detail at atomato.co.

After checkout, keep the thank-you page clear, and save review, referral and reorder asks for later, using timing and softer surfaces. See our guide on how to ask for Shopify reviews, referrals, and reorders without another checkout interrupt.
