Customers opt in to hear from your brand on WhatsApp, then you reach them two ways.

Automations fire off something they did, like abandoning a cart or waiting on a restock. Icebreakers are broadcasts to your list or a segment, used for launches, private sales and VIP access.

The difference from email and SMS is that people reply. That changes what you send, because a message designed to start a conversation looks nothing like a message designed to drive a click.

No. It's additive.

More touchpoints mean more impressions and more revenue, and each channel is good at different things. Use WhatsApp for launches, back-in-stock, final-hours urgency, VIP access, cart recovery and product questions. Keep email doing what email does well.

Don't make the channels fight each other.

We've set out the full case for adding it as a layer instead of a swap here: Should DTC Brands Add WhatsApp to Their Retention Stack?

It's strongest there, though not exclusively.

WhatsApp is the dominant messaging platform across most of Europe and much of the world, and it's particularly valuable for UK and EU brands because SMS never took hold there as a marketing channel the way it did in the US.

If your customer base is almost entirely US, SMS is usually the better second channel and we'll say so.

Yes, and it's the part that's changed most.

An assistant trained on your brand story, products and tone can talk to every customer at once, in any language, at any hour. That used to cost the founder's time or a support team.

Speed is what makes it work. Replying while someone is still on your site genuinely moves conversion.

The warning is the same as everywhere else though. Point AI at producing more generic messages and you'll make the channel worse, not better.

List growth is the first project, before any campaign.

The tactical detail sits in WhatsApp for Shopify: How to Launch Faster and Make It Convert, which covers where the opt-ins come from, which automations to turn on first, and the week-by-week rollout.

It's the piece most brands underestimate. A WhatsApp programme with no list is just a channel you're paying to have switched on.

CoCo AI, who we partner with on WhatsApp.

It's Shopify only, so if you're on another platform we'll be straight with you about what does and doesn't transfer.

We do, in-house. Copy, design and build sit with your account team. You approve, we produce.

Usually, though not always.

It works fastest when your products raise questions before purchase, when your traffic is mobile-heavy, and when your customers already use WhatsApp daily. It's a weaker fit for very low-consideration, low-AOV products, and for one-time purchases with no repeat cycle.

It isn't available at all for CBD, alcohol or adult stores.

Adam has written the longer version of this argument, including where the channel doesn't earn its place, in Should DTC Brands Add WhatsApp to Their Retention Stack?

Yes.

What changes is the scope. Below eight figures your leverage sits in the core four flows executed brilliantly, steady list growth and a sensible campaign cadence. Any agency pitching hyper-segmentation and complex VIP flows at that stage is selling you workload, not results.

The one case where we'll say no is a product that doesn't lend itself to repeat purchase at all. Then your money is better spent on acquisition, and we'll tell you that on the call.
