Email marketing agency in London

We plan, design, write and build email programmes that turn subscribers into customers and customers into regulars. Flows that run every day, campaigns that land in the inbox, and reporting on the revenue they bring in, not just the opens.

What an email marketing agency should actually do for you

Most brands already have an email platform. What they usually don't have is a system: a welcome series that sells, abandoned cart emails that recover the basket, post purchase emails that earn the second order, and a campaign calendar that doesn't rely on someone remembering to send something on a Friday.

That system is what we build. We start with your customer data and your CRM, work out where revenue is slipping out, and then build the flows and campaigns that close those gaps. Everything is written by native English copywriters, designed mobile first, and checked by a strategist before it goes out.

Lifecycle flows first, campaigns on top

Flows are the automated emails that go to one person at the moment they do something: join your list, browse a product, leave a basket, buy, or go quiet. They usually earn far more per email than campaigns because they are relevant by design. We get these running first, then build your campaign calendar on top of them.

For eCommerce brands that means welcome, browse abandonment, abandoned cart and checkout, post purchase, review requests, replenishment, winback and sunset flows. We have written up the nine flows every ecommerce brand should have running if you want to see the thinking.

Campaigns that people open

Launches, restocks, gift guides, Black Friday, newsletters and seasonal sends. Each campaign is planned against your calendar and your segments, so the right people get the right message and your whole list isn't hit with every send. You can see examples of our design and copy on the campaigns page.

Deliverability, because none of it matters in spam

We check your sending domain authentication (SPF, DKIM and DMARC), warm up new sending properly, suppress contacts who never engage, and keep an eye on bounce and complaint rates. A smaller list that opens beats a big one that doesn't, and inbox placement is the foundation everything else stands on.

eCommerce brands on Shopify, WooCommerce and similar; B2C brands without an online store, such as gyms, salons, subscriptions, apps and hospitality; and B2B companies with longer sales cycles. We are based in London and work with brands across the UK, Europe and the USA.

Frequently asked questions

How much does an email marketing agency cost?

Our set modules start from $500 each, bundles run from $4,700 to $7,500 depending on your business type, and retainers to keep the system running start from $299 a month. Every price is on the pricing page, so you know the cost before the call.

How quickly will my first flow be live?

Your first flow is briefed before the kickoff call and delivered within the first 7 to 14 days.

Which email platforms do you work in?

Klaviyo, HubSpot, Brevo and GoHighLevel day to day. We also handle ESP migrations if you are moving from one platform to another.

Do you write the emails or just design them?

Both. Native English copywriters write every email, a designer builds it, and a strategist reviews it before anything is sent.

Do you only work with London brands?

No. We are based in London and work with brands across the UK, Europe and the USA.

Let’s look at your email together

Thirty minutes. We look at what you sell, how people buy it, and what your systems currently do. You will leave with at least one thing worth fixing, whether or not you work with us.

Half to start. The rest only when we hit your number. We agree your baseline and your Performance Threshold on the call, in writing, before any work starts. You pay half to begin, and the second half is only due if we reach it within 21 days. How the guarantee works
