How to 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 with a discount offer collecting signups, and that popup is worth its place. The issue arises 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 it looks absurd. On mobile, where most of the traffic is, it can cover the entire screen on first paint, so the shopper closes everything before reading a word.

There is a quieter 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 with a survey of the current interruptions

Before adding anything, list everything that appears without the customer 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 is being limited by lost interest rather than by the offer.

Keep the popup and tune it

Removing the popup is not the answer; it is still the main contributor to signups. Tune it instead:

Trigger on intent, not on arrival. Fire after a 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, or who are current subscribers, should not see it a third time. Longer suppression for repeat visitors has a minor effect on signups and a major effect on 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 an email and phone field stacked together with two consent checkboxes.

Add an optional path the shopper chooses

The second channel should be one the shopper voluntarily picks. That is how a notification feed works: a bell icon in the header. It sits there quietly, shows a count when something is new, and only opens on tap. It does not cover the page, so it can hold several messages at once without stacking overlays.

Useful things to put in that feed:

A signup card — 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.

This email-first, SMS-second capture is run by Triquetra Health and is inside its feed; the Triquetra case study shows that it is alongside the store's existing email and SMS programme.

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

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

Order status and subscription updates, which bring customers back to open the bell again.

Atomato is the app we build for this surface. It installs the bell and feed beside your existing popup without removing it, and it is only for on-site messages, not for sending 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 with, keeping segments, flows, and consent records in one place. The common destinations are Klaviyo, Mailchimp, and Omnisend, plus Attentive or Drip where those are in the stack.

One point worth clarifying, because it comes up often: SKIO is a subscriptions app, not an email destination. It is an integration for subscription stores and is useful for targeting subscribers — 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. A signup card shown on a product or collection page after real engagement performs better than the same card fired on every landing.

Go multi-step: email first, then phone. Ask for the phone number on the confirmation step with its own consent language, and accept that only some will give it.

Target by page, cart state, and visit history. New visitors can see the discount offer; returning visitors who already subscribed can see restocks or order 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 and leave the other available.

Measure honestly, by source and step: popup submits, feed opens, feed signup submits, and phone numbers added after email. Check unsubscribe rates and how often the popup was shown to people who were never going to fit. Those numbers tell you whether the second path is bringing in new subscribers or just shifting them.

Be careful with conversion-rate claims. Attributing a signup surface to revenue 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

Pick one change this week: raise the popup's trigger threshold and lengthen suppression for returning visitors. After that, add the feed as an alternative path and put a signup card in it. Sync your ESP from day one so nothing is stranded on-site.
