If you run a consumer brand in the UK or Europe, there is a good chance you already have access to one of the most useful retention channels available to you.

And there is also a good chance you are thinking about it in completely the wrong way.

I am talking about WhatsApp.

Most brands still treat WhatsApp as another messaging channel. Another place for campaigns, shipping updates, promotions and abandoned-cart reminders.

I think that massively undersells what it is.

Because WhatsApp has the potential to sit much closer to the subscription customer journey, especially during the period between purchase and proof.

This is the simplest way I have found to think about it.

Email gives you an inbox.

A telephone gives you a conversation.

WhatsApp gives you elements of both.

You have the delivery flexibility of email.

Text.

Images.

Illustrations.

Video.

Links.

Education.

But you also have the intimacy of a phone.

The customer replies.

They ask a question.

They tell you they forgot to take the product.

They send you a photo.

They tell you they have been using something for three weeks and still do not feel anything.

You are suddenly no longer broadcasting at someone.

You are talking to them.

And in the UK, you are doing it somewhere they already spend time. Ofcom reports WhatsApp usage among 90% of UK adults, while WhatsApp penetration is around 90% in markets such as Spain, Portugal, Ireland and Italy, and 85% in Germany.

That matters.

You are not asking the customer to download another app, remember another password or build another behaviour.

The inbox is already in their pocket.

I call this feedback latency.

It is the time between someone starting to use a product and receiving enough feedback to decide whether the product is doing what they hoped.

With coffee, feedback latency is about 90 seconds.

You make the coffee.

You take a sip.

You know whether you like it.

Nobody needs six weeks of coffee education to work out whether the coffee tastes good.

The main retention problem might simply be replenishment.

Did the bag run out?

Did they prefer another roast?

Should they skip the next delivery?

Now think about skincare.

Haircare.

Sleep supplements.

Gut products.

Collagen.

Many wellness products require repeated use before the customer feels they have enough evidence to judge the purchase.

That creates a dangerous gap.

A customer reaches day seven.

Nothing obvious has happened.

Day fourteen arrives.

Still not sure.

Then another billing notification appears.

Now you are asking someone to make a second financial commitment while they are still wondering whether the first one worked.

This is where I think many brands misunderstand churn.

Sometimes the cancellation was created weeks earlier.

The promise was wrong.

The expectation was wrong.

The customer was not using the product consistently.

The pack size did not match the billing cadence.

Or nobody explained what they should realistically expect during weeks one, two and three.

I wrote about this previously as acquisition churn.

WhatsApp does not rescue a bad product or a broken offer.

But once those fundamentals are right, it gives you somewhere to manage the period between purchase and proof.

This is where my thinking starts to diverge from most WhatsApp strategies I see.

I do not think the first 28 days should look like this:

Welcome.

Day-seven check-in.

Day-21 review request.

Billing reminder.

Done.

That is an automation.

It is not a relationship.

If your product depends on repeated usage, your first job is helping the customer use enough of the product, consistently enough, to give it a fair opportunity to deliver the expected experience.

Wellness brands should borrow one important mindset from healthcare.

Adherence matters.

If something only delivers its intended benefit when somebody follows the protocol, then communication around usage becomes part of the customer experience.

There is useful evidence behind that principle. One randomised clinical trial used 55 text, image and audio WhatsApp messages across 16 weeks as part of a medication-adherence intervention for people with hypertension and diabetes. Another randomised smoking-cessation trial delivered 60 WhatsApp support messages across three months and reported higher abstinence rates than usual care. These are clinical settings, not supplement marketing, but they demonstrate an important behavioural point. Sustained support looks more like a programme than the occasional reminder. Read the medication-adherence study and the smoking-cessation study.

I would think about the first 28 days as a habit-building window.

The first 28 days are the behavioural window. The 90 days are the retention system that sits around it.

The first month is where you establish usage, adherence and routine. The following two months are where you reinforce that behaviour, manage expectations, solve friction and see whether it translates into retention.

And during that first behavioural window, I think WhatsApp has four jobs.

Help the customer establish usage.

When are you taking it?

What routine does it fit into?

Are you still taking it consistently?

Did something get in the way?

The objective is not to nag somebody every morning.

It is to help product usage become part of their routine.

The customer who takes the product every day should not receive the same journey as someone who keeps forgetting.

Which leads to the next job.

Some information deserves more attention than an email buried between a Deliveroo receipt and a LinkedIn notification.

A thirty-second video showing exactly how to prepare a product.

An illustration explaining what somebody should expect during the first few weeks.

A simple guide to when and how to use something.

A message explaining why somebody should not expect an immediate result.

WhatsApp supports text, images, video and richer conversational experiences, which makes education feel less like another lifecycle campaign and more like guidance delivered when somebody needs it. WhatsApp describes its Business Platform around these richer conversational experiences.

You do not need to dump your entire content library onto somebody.

You identify the handful of things that matter most to successful product adoption.

Then you make sure those messages land.

This might be the biggest opportunity.

Someone replies:

“I don't think I'm doing this properly.”

“My powder isn't dissolving.”

“I haven't noticed anything yet.”

“My next order is coming but I still have half a tub.”

Now you have information many brands normally receive when the customer is already inside the cancellation flow.

That is too late.

WhatsApp gives you the opportunity to surface friction earlier.

AI handles straightforward questions.

A human takes over where judgement, sensitivity or nuance matters.

WhatsApp permits automation inside customer-service conversations while requiring businesses to provide a clear path to human escalation. That requirement sits inside WhatsApp's Business Messaging Policy.

That makes WhatsApp more than another CRM channel.

It becomes a support surface.

This is where the model becomes much more interesting.

Do not ask questions for engagement.

Ask questions because the answer changes what happens next.

Are you using the product every day?

Have you started noticing anything?

What has been difficult?

Do you have too much product?

Do you need help?

Someone reporting early progress needs reinforcement.

Someone struggling with adherence needs another intervention.

Someone using the product exactly as intended but seeing no progress needs a different conversation.

Someone reporting a genuine issue needs support.

Same customer journey.

Different paths.

And that is where WhatsApp stops behaving like another broadcast channel and starts behaving like a real customer relationship layer.

The question is not:

“How many WhatsApp messages should we send in 28 days?”

The question is:

“What does this customer need from us during these 28 days?”

For one person that might mean eight meaningful interactions.

Another might need more.

Another might need far less because everything is working perfectly.

Cadence should follow customer behaviour.

The moment we put an arbitrary message ceiling on the programme, we start designing around the channel rather than the customer.

There is also an economic reason to think conversationally.

Meta's current WhatsApp Business pricing varies by market and message category. Marketing, utility, authentication and service messages are treated differently. When a customer messages a business, a 24-hour customer-service window opens where service replies are free.

So a genuine reply is not something to fear.

A reply is the point.

The customer has told you something.

Now the conversation has somewhere useful to go.

Then there is community.

I see one-to-one WhatsApp and WhatsApp community as two separate, complementary jobs.

One-to-one is where the brand coaches, educates, supports and listens.

Community creates the social layer.

Other customers exist.

Other people have questions.

Other people are building the same routine.

People share experiences.

People see how others use the product.

The brand starts to become more than something arriving in a cardboard box every thirty days.

There is trust in seeing other people participate.

There is accountability.

There is belonging.

And there are economies of scale in answering questions that many customers share.

But I would not automatically drop every new WhatsApp subscriber into a community.

The invitation should have a purpose.

“Join our WhatsApp group” is weak.

“Join 800 other people following the same 30-day programme” is different.

One-to-one and community together create something email struggles to reproduce.

Private coaching when you need it.

Social reinforcement when you do not.

This is where I want brands to stop obsessing over open rates.

WhatsApp open rates are interesting.

They are not the business case.

Clicks are interesting.

They are not the business case either.

I want to know what happened to customer behaviour.

Did more customers use the product consistently?

Did we identify customers who were struggling before they cancelled?

Did more people reach order two?

Did fewer people cancel because they had too much stock?

Did customers who engaged with onboarding retain better?

Did month-three hold improve?

That is the scorecard.

There are useful signals from brands already using WhatsApp.

Jimmy Joy's Klaviyo case study reports that WhatsApp generated nearly 30% of Klaviyo-attributed revenue during its Black Friday early-access campaign while reaching less than 5% of its total marketing list. The brand describes WhatsApp as an added layer of intimacy and immediacy over email.

Dermalogica has taken the idea further, using one-to-one WhatsApp skincare consultations alongside campaigns. Its published case study reports a 40% click-through rate on one Valentine's campaign and describes WhatsApp consultations as a way to provide personalised skincare advice directly to customers.

Those examples prove something useful.

People engage.

People converse.

People buy.

They do not yet prove the thing I am most interested in.

Retention.

Did WhatsApp materially change who was still paying at month three?

Did adherence improve?

Did the intervention create more second orders?

That is the experiment I want to run.

You need a holdout.

Same product.

Same offer.

Same onboarding fundamentals.

A percentage of the cohort does not receive the WhatsApp intervention.

Then you follow the cohorts.

That is where this stops being a messaging experiment and starts becoming a retention experiment.

There are also boundaries.

If you operate in wellness, supplements or health-adjacent categories, your educational programme still has to respect advertising and product-claims rules. The ASA is explicit that supplements are treated as food rather than medicine and cannot make claims to diagnose, treat or prevent disease.

Opt-in matters too.

WhatsApp requires businesses to have the person's mobile number and permission to contact them, and UK electronic marketing rules require consent to be specific and informed where consent is relied upon. WhatsApp's Business Messaging Policy and the ICO's electronic marketing guidance are worth understanding before building the acquisition layer.

Which means the opt-in itself needs a value proposition.

Not:

“Subscribe to our WhatsApp.”

More like:

“Get 28 days of product coaching, check-ins and support on WhatsApp.”

Now I know why I am giving you my number.

This is not right for every brand.

If your product proves itself in a sip, there is less for WhatsApp to solve.

If nobody on your team is going to answer when a customer replies, do not open a channel that implies someone is listening.

And if acquisition is not already working, this is the wrong problem to solve first.

But if you are already acquiring customers at meaningful volume and the bigger opportunity now sits in what happens after the first purchase, this is where I think things get interesting.

I have partnered with Coco AI, who have the WhatsApp infrastructure and implementation capability.

My side is the retention playbook.

The customer journey.

The behavioural logic.

What gets asked.

What happens next.

Where education sits.

Where AI sits.

Where a person needs to step in.

And how we measure whether any of this changed retention.

For the remainder of 2026, I want to work with five UK or European consumer brands to build and test this properly.

Five.

Not fifty.

I am particularly interested in supplements, wellness, skincare, functional food, drinks and other replenishment-led categories.

And I am looking for brands where acquisition is already working.

You know how to acquire customers.

You have meaningful volume coming through the front door.

Now you want to get more serious about what happens after they buy.

I want to work closely enough with those five brands to understand what works across different products, feedback windows and customer behaviours.

Then we measure it.

Order two.

Month three.

Usage.

Engagement.

Churn reasons.

Holdout versus intervention.

The objective is not to “launch WhatsApp.”

The objective is to build a 90-day retention system where WhatsApp acts as the conversation between purchase and proof.

If you run one of those brands, reply to this email.

If you know a founder who is doing strong acquisition numbers but has not yet taken WhatsApp seriously as a retention channel, forward this issue to them and introduce us.

I only need five.

And I want the brands involved to help shape what this playbook becomes.

If you’re serious about building this into your retention stack, apply to work with me.

But if this issue made you rethink what WhatsApp might do for your customer experience, reply.

That is probably the right conversation to have first.
