An outbound mechanic for agencies

Just lost a client? Email their competitor.

It's called the magic email. Started on a bus in 2016. Won us 10+ clients since, including some of our biggest. Here's exactly what it is, why it works, and when not to bother with it.

It started on a bus.

YEAR   2016
SECTOR   Vitamins & Supplements
% OF REVENUE   ~40%
NOTICE   30 days
MOOD   Rubbish

EMAILED   1 person
REPLIES   1, a month later
PITCHED   No
RESULT   8-year client

I was on the bus home from work. My phone rang. It was our biggest client, a vitamins & supplements brand, around 40% of our revenue at the time. They were serving notice.

Yes, 30 days. I was an idiot.

I got home upset. Opened my laptop. Found the CMO of their direct competitor. Wrote him an email. Honest, slightly long: we'd been working with the client for years, they were taking stuff in-house, we'd got ideas, would he be open to a chat.

I couldn't think of anything to put in the subject line. So I just wrote the client's name.

A month went by. I'd forgotten about it. Then he replied: "Sorry for the delay, would be interested in an informal meeting." I went in. They appointed me at lunch. I never pitched.

They stayed with us for 8 years.

Ten years on, that subject line is still doing the work. I've forwarded that original email to 71 people. Everyone who's used it has had a response. Some have won clients off the back of it. We've won 10+ ourselves, including some of the biggest we've ever had.

The whole unlock is the subject line.

Six things that make it work. Or not.

/ 01
Send it to the CEO. Not the marketing manager.
If you go in via the marketing team, you're a supplier. If you go in via the CEO, you're a partner, even if they forward it down the line. You've already got buy-in by the time their team replies. Don't email CMOs either; they're too in the weeds and likely to gatekeep.
/ 02
Talk results. Not channels.
CEOs don't care that you do PPC, SEO, or paid social. They care about revenue, growth, market share. "We helped X grow by Y%" beats "We're a full-service performance agency" every single time.
/ 03
Send 5, not 500.
We tried scaling this. Sent 350 templated emails to a list of beauty brands. Got 2 responses. The mechanic dies the moment it stops feeling personal. Every email needs to be re-written for the specific company, the specific moment.
/ 04
The niche-er the sector, the better it works.
In lockdown we lost a menopause-clothing client. Emailed 10 of their direct competitors. Got 8 replies, 6 meetings, 3 clients. The narrower the space, the more they care what their rivals are doing.
/ 05
You need a story. Not just an offer.
This doesn't work without a real reason to send it. A pitch you've just lost. A client who's just left. A competitor that just won someone you should have. If you've got nothing to point at, the email has nothing to do.
/ 06
It puts you in control. Use that.
When someone replies, you set the terms. You're not pitching for a brief. You're showing them something about their market they didn't see. That changes the dynamic of every conversation that follows. Including pricing.

It's worked enough times to bet on.

Not every email lands. Not every reply turns into a client. But the ones that have shaped the agency over the last decade have mostly come from this. Not from inbound, not from referrals, not from cold lists.

2016
Vitamins & supplements client → Direct competitor
Lost our biggest client on a 30-day notice. Emailed the CMO of their direct competitor. Subject line: the lost client's name.
8-year client.
Never pitched.
2020
Menopause-wear brand → Niche competitors
Lost a niche client in lockdown. Emailed 10 direct competitors in the same space.
8 replies, 6 meetings,
3 clients won.
2022
Company-formation client → UK rivals
Lost a UK company-formation client. Reached out to three direct rivals in the same space. Same template, same subject-line trick.
2 wins, multiple meetings,
repeat work.
2025
Healthcare research platform → Direct competitor
Lost a £10k retainer in November. Emailed the CEO of a direct competitor. Subject: [Lost Client] - In Confidence. He forwarded to his CMO.
Won February 2025.
Working with their team now.

Important, because the space is full of nonsense.

This isn't
  • Mass cold email (we tried 350, got 2 responses)
  • An always-on demand channel
  • A way to fill a quiet pipeline from scratch
  • Generic outbound dressed up
  • A 'system' you can hand to an SDR
This is
  • One tactic, used five to ten times a year
  • Triggered by a real event in your business
  • Written by you, every time, from scratch
  • Aimed at the top of the org, not the middle
  • Best used alongside a working sales process

Most of us are bad at sales.

Not because we can't be. Because we're scared of it. Or bored of it. Or worn out from too many months where nothing replies to anything. Inertia wins. The pipeline doesn't get built. The hours don't get put in.

This breaks that. When you send five of these and a CEO actually writes back, it's a real hit. A proper one. The first thing in months that's made you want to send another one.

That's what this is for. Not pipeline. Not "sales motion." It's the thing that gets you off the floor and back into doing the work, because the win is fresh, the reply is real, and the next email actually feels worth writing.

Hence the name.

It's not a silver bullet.
But every now and then, it feels like one.
Ten years on, still the best line for it

Agencies who already win work, and want to win more of the deals they should be in.

  • You've got a working sales process Inbound, referrals, network. Something already keeps the lights on.
  • You just lost a pitch, a client, or watched a rival poach one You can name the company. You can name the moment. That's the whole prompt.
  • You hate generic outbound Because most of it is bad, and it makes your agency look bad too.
  • You'd rather have ten right conversations than a thousand wrong ones If "spray and pray" makes you wince, you're in the right place.

Three ways in.

Pick whichever fits where you are. The first one's free, because the work is already done.

I'll set it up
£1,500

A focused one-off engagement off the back of a specific moment. I find the right competitors, build the list, write the emails for your situation. You send them, take the meetings, keep the wins.

For agencies sat on a recent loss who want it executed properly, fast
/ 03
I'll stay involved
Let's chat. Won't cost loads.

A retained engagement across multiple triggers as they come up. Lost pitches, lost clients, market moves. We build this into a repeatable layer that sits on top of how you already win work.

For agencies who want this layered into how they win work, not used once and forgotten

I'm Simon.

I've been in digital since 2003. Ex-Googler. Started Curated Digital not long after, and have been running it ever since, through the good years (23 people, big retainers) and the leaner ones (six of us now, more interesting work, fewer headaches).

This page isn't part of Curated. It's something I've been doing on the side for the better part of a decade.

I've also got ADHD. Diagnosed late. And I hate structure. Process, repetition, the "send 50 templated emails a day forever" grind. None of it takes. I'm hopeless at the methodical doing that most agency growth depends on.

But on the day we lose a client, I can sit down for two hours and write five really good emails to people who should already be talking to us. And that, weirdly, has worked enough times over ten years to bet on.

So this isn't a system. There are no pillars, no automations. It's one tactic. It's worked. I've forwarded the original email to 71 agency owners over the years, and most of them have won work off the back of it.

Hence this page.

Tell me about a client you just lost.

Get in touch. Tell me who you've just lost, what they were worth, and where it leaves you. I'll come back with some honest thoughts on what I'd do if I were sat where you are. Could be the magic email. Could be something else entirely. Either way: no call, no deck, no follow-up if it isn't useful. No strings.

Something went wrong. Please email simon@curated-digital.com directly.

Cheers. Got it.

I'll come back to you within 24 hours, usually sooner. Honest read on what I'd do, no follow-up unless you want one.
