You've already paid for these contacts

Before the three concrete cases, the reasoning needs stating. It fits in one sentence, and it's what makes everything else obvious.

The contact is bought, the email is free

When you advertise, you aren't paying for customers. You're paying for visits, a small share of which leave you a way to get in touch: an address, a number, a first name.

That contact has a price, and the price is already settled. You paid it the day the person arrived. Whether you write to them or not changes nothing about what you spent.

Writing to them, on the other hand, costs almost nothing. A few euros of tooling and an hour of setup, once.

So you're comparing a contact already bought with a contact you'd have to buy again through advertising. That isn't even a trade-off, it's obvious. And yet most companies re-buy instead of following up.

This isn't a newsletter

Let's clear the misunderstanding straight away, because it puts off three quarters of people.

I'm not talking about sending a monthly bulletin to your whole list. That earns almost nothing, everyone gets too many, and nobody opens them.

I'm talking about a message triggered by a specific action:

• a basket filled then abandoned partway through;
• a booking started and never confirmed;
• a quote request left without an answer;
• a sign-up for an offer that never turned into a purchase.

The difference isn't in the quality of the writing. It's in the trigger. A message arriving at the right moment because someone just did something has nothing in common with a message arriving because it's Thursday.

"I don't want to bother people"

It's the objection I hear most, and I'll be direct: if you're afraid to contact someone who started something on your site, the email isn't the problem.

That person filled in a form. They put items in a basket. They opened your calendar. They showed interest and didn't finish, usually for an ordinary reason: a phone call, a child needing something, a hesitation over a detail.

Writing to them once isn't harassment. It's doing your job.

That said, the nuance matters, and I'm not defending just anything. You don't write six times. You don't invent urgency. You stay consistent with how you speak to your customers the rest of the time. A useful message, sent at the right moment, bothers nobody.

You paid to obtain that contact. Not using it means paying for them a second time, in advertising.

E-commerce: this isn't an optimisation

Let's start with the ground where nobody argues any more, because the case has been settled there for fifteen years.

It's a condition of survival

Ask any online retailer who lasts. None of them will tell you follow-up is an improvement. All of them will tell you it's basic, on a par with payment or delivery.

The reason is arithmetic. Out of a hundred people who fill a basket, most don't confirm. That isn't an accident, it's normal behaviour for an online buyer: they compare, they pause, they come back.

A shop without follow-up loses all of them. A shop that follows up recovers a share, at a cost close to zero.

Cold, warm, hot

The jargon is what it is, but it describes reality well.

• Cold: they don't know you. Reaching them costs a lot.
• Warm: they've seen you, they've looked, they've done nothing.
• Hot: they acted. A basket, a form, details left behind.

All your advertising exists to move people from cold to hot. That's the long, costly, uncertain part of the work.

And once they've arrived at the top, plenty of companies let them slide back down without doing anything. Retargeting exists to catch them, but it costs more every year and goes back through advertising, when you have their address in your own records.

A sequence that repaid two years of my fee

One case I remember, five or six years ago, on an online shop.

Nothing sophisticated: four or five emails, triggered on abandoned baskets and on sign-ups that never converted. Set up once, then left alone.

What that sequence generated over time repaid two years of my fee. Not two months. Two years.

I don't tell that story to sell myself, but because the gap is revealing: the most profitable part of the work was neither the most visible, nor the longest, nor the most expensive.

Before everything else

Which is why I place this very high in the order of priorities.

If you sell online and have no follow-up in place, this comes before a redesign, before a new channel, and before paying someone to feed your social accounts. It takes less effort and produces more, immediately.

All your advertising exists to bring people to the top. Not following up means watching them slide back down.

Bookings: capture before the end

Second ground, less obvious, and where I've seen the sharpest differences in recent years.

The problem with single-block journeys

A classic booking system runs in one go: you pick a date, options, a number of people, then give your details right at the end, just before paying.

The consequence: everyone who stops partway is lost for good. They spent time with you, they were interested, and you have no way of reaching them. You don't even know they came.

That's exactly why splitting a journey into steps changes everything: you're no longer measuring a result, you know who stopped and where.

One email, 10 to 15%

Here's the concrete case, at one of my clients.

The booking journey is split, and details are collected before final confirmation. As a result, people who abandon partway remain reachable.

We put one email in place. One, automatic, triggered when a booking is left unfinished. Nothing else.

From the first month, that email represents 10 to 15% additional revenue. Not 10% more clicks, not 10% more opens: real revenue, on bookings that wouldn't have existed.

Setup time is measured in hours. After that it runs on its own.

The trade-off: asking earlier

You can go further, and it's an interesting arbitrage to put on the table.

Current practice says to ask for details as late as possible, so as not to slow anyone down. The opposite is defensible: ask for a first name and an address before opening the calendar.

You lose a few people at the door, certainly. But you become able to contact everyone who didn't finish, instead of a handful.

Is it worth it? That depends on your average order value and your volume, and it's something to test rather than decide. But at least ask the question, because nobody does.

Why your tool won't let you

If you try all this with a subscription booking product, you'll hit a wall quickly.

These tools are built for the majority, which is entirely legitimate. But they show you the final result, rarely the step-by-step detail, and they almost never let you trigger your own messages on your own criteria.

That's the whole subject of the standard tool versus the one you control. Here the difference isn't a matter of comfort, it's measurable.

One automatic email, triggered on an abandoned step, is worth more than most redesigns.

Quotes: the one who doesn't answer

Third ground, and probably the one that concerns most of the people reading this.

Stop asking for a quote request

The classic quote form asks for a lot and gives nothing. Describe your project, leave your details, we'll get back to you.

Replace it with a booking: the person picks a slot, you call them back. That's the principle of the first step, and the conversion gap is stark.

And above all, split it. Details first, specifics afterwards. Whoever stops after the first step stays reachable.

Someone who doesn't pick up hasn't said no

You call, there's no answer. You leave a message. Nothing.

Most companies stop there and file the contact as lost. It isn't. They were in a meeting, on site, driving. They forgot.

An automatic email then goes to everyone who hasn't responded within forty-eight hours. Short, no reproach: I tried to reach you, here's a link to pick a time that suits you.

One setup, and you recover a share of people you had already paid for.

Second and third follow-ups

The first follow-up captures most of it. The later ones add less, but the gain is real, especially in B2B.

There, cycles are long, people are genuinely busy, and a file can sit for three weeks without that meaning a refusal. A follow-up at day seven and another at day twenty-one recovers business everyone else had written off.

Beyond that, stop. You're tiring people for nothing, and damaging an image that took you a long time to build.

A contact who doesn't answer hasn't refused. They were interrupted, and nobody came back to them.

On one condition

All that's left is to honour the promise in the title honestly, by saying when it doesn't hold.

Without volume there's nothing to recover

Everything I've just described assumes something is happening on your site. Baskets, bookings started, forms begun.

With a hundred visits a month there's nothing to follow up. Ten per cent of a figure close to zero stays close to zero. The problem isn't follow-up, it's the absence of traffic to analyse.

These mechanics work when real acquisition is running alongside: advertising, search, local reputation, whichever channel you like, but there has to be one bringing people in regularly.

Which is also why I always put the question of the advertising budget before the question of tools.

A trick, and its limit

You'll often read that you should exclude your existing contacts from your campaigns, so as not to pay twice for the same person. The idea is sound on paper.

In practice it's less clear-cut. Touchpoints multiply, someone may need to see you three times before acting, and measurement gets blurry. It isn't black and white.

Test it yourself rather than applying it because you read it. That goes for this trick as for the rest of what I write.

Your ten minutes

Concretely, here's what I'd do if you gave me ten minutes:

• identify the step in your journey where you lose the most people;
• check whether you have their details at that point, and if not, ask earlier;
• write one email, short, with no promotion in it;
• trigger it automatically on that step;
• look at what it produces after a month, before adding a second.

No strategy, no redesign, no new tool. One step, one message.

The most profitable part of your digital presence is the part you've already paid for and aren't using.

If you'd like to find out where your sleeping contacts are, write to me. We find the step in one conversation, and one email is often enough to change the year.
