Email Marketing & CRM Infrastructure
Your list isn't a database. It's a front row. Ooco turns founder-led brands' email lists into high-converting digital editorials that get opened, read and shopped. No robotic templates. No auto-generated spam. Just emails people actually wait for.
Brands that trusted Ooco with their inbox







An open letter to every founder whose "newsletter" reads like it was written by a photocopier.
Somewhere along the way, brands were told that email had to be beige. Stiff subject lines. Auto-generated blocks. "Hi {FIRST NAME}, we thought you might like…", sent to twelve thousand people who immediately thought no, I would not.
Here's what the data proves: email is still the highest-converting channel your brand owns. Not rents. Owns. No algorithm deciding who sees you, no ad auction inflating overnight. Just you, arriving in the one place your customer checks before she's even out of bed.
"Your emails should be your best-dressed sales channel: a publication, not a print-out."
At Ooco we build emails like editors build magazines. Every send has a point of view, a look, and a job to do. We take the strategy seriously so the send can feel effortless, because people buy from brands that feel alive, and nothing kills a brand faster than sounding like software.
And one more thing, while we have the column inches: great email is not a Chanel bag. It should not be affordable to the minority only. That's why Ooco starts at £49 a month and scales to a full CRM engine, so the brand you're building at your kitchen table gets the same calibre inbox as the ones with a floor of marketers.
Never stare at a blank "compose" again.
That £49 a month is the Weekly Spark: subject lines worth stealing, design prompts and one sharp conversion tip, landing in your inbox every week — plus the Spark Telegram, me on hand 1-1 and a corner full of founders who get it. Your community is waiting to hear from you. Now you'll always know what to say.

We've been really happy with the output and I've enjoyed working with you. Your support has been really valuable.
Harriet has been amazing. The work in HubSpot has helped, and the training she delivered was so clear for our team.
You've been great to work with and really installed a foundation of work that has helped the company.
The woman in your inbox
I'm the founder (and the entire editorial desk) of Ooco. I've spent years inside the CRMs of wellness, beauty, service and tech brands, from scrappy founder-led labels to platforms like YouCanBookMe and Ultumus, turning "we should really do email" into the channel that out-earns everything else.
My whole thesis is simple: your customers are already loyal to inboxes. They're just not loyal to boring. So I build emails like a magazine editor and measure them like an analyst: taste in the front, dashboards in the back.
And when you work with Ooco, you work with me. No junior account manager, no brief lost between five people, no telephone game. Just senior, hands-on attention on your inbox from the person actually doing the work.
When I'm not in your CRM, I'm writing Sent., my letter on building community through email (and building a business out loud).

All the majors: Klaviyo, Mailchimp, HubSpot, Flodesk and friends. On Signature Send and the Retention Overhaul I manage the tech completely, so you never have to learn the platform. If you're pre-platform, I'll recommend and set up the right one for your brand.
Campaign work shows up immediately. Our best restyle produced a +100.6% conversion spike on the very next send. Infrastructure compounds: the Retention Overhaul is built in 8 weeks, and those flows keep earning for you long after they're switched on.
Especially then. Small lists are where community is built. Weekly Spark exists precisely so you grow a list that loves you from day one, instead of fixing a cold one later. And you won't grow it alone: the Spark Telegram puts me, and a huddle of founders doing the same thing, in your pocket. Great email shouldn't be affordable to the minority only; that's the whole point of the £49 tier.
We start with the Master Audit and strategy, so we know exactly where your revenue is leaking. Then I build your three core flows: welcome, nurture and win-back. Everything lands in your private Inbox Hub as we go, so by week eight you own a permanent retention engine, not a report.
Ooco exists because auto-generated email is beige and everyone can smell it. Strategy, copy and design are done by an actual human with actual taste. Tools assist, they never author.
No mystery, no hard sell. Three steps from "hello" to inbox glow-up.
A relaxed 20 minutes. Tell me about your brand, your list and where email's falling flat. No pitch deck, no pressure.
