The Email Marketing Agency London Businesses Trust to Turn Email Into Revenue
Walden Waves is an email marketing agency based in East London (Royal Docks, E16). We design, write, and manage email marketing campaigns for businesses across London — campaigns that get opened, get clicked, and drive real revenue from the audience you’ve already built.
End-to-End Email Marketing That Works
Email marketing has the highest ROI of any marketing channel — £36 back for every £1 spent when done properly. The problem is most London businesses either don’t email consistently, don’t segment their lists intelligently, or send campaigns that nobody opens. We fix all three. From email strategy and list management to campaign design, copywriting, automation, and monthly reporting — our team handles every part of your email marketing so your list becomes your most valuable asset.
Email Marketing Strategy
Before a single email goes out, we build a strategy around your audience, your goals, and your customer journey. Which segments to target. What to say at each stage. How often to send. And which metrics actually tell you whether it’s working.
Email Campaign Design & Copywriting
An email nobody opens is a wasted opportunity. An email nobody clicks is a beautiful waste of design budget. We write subject lines that get opened and body copy that gets clicked — for London businesses that want emails people actually read.
Email Automation & Flows
Your email list is making money while you sleep — or it should be. We build automated email flows for London businesses: welcome sequences, abandoned cart flows, post-purchase nurture, re-engagement campaigns, and drip sequences that work around the clock.
List Management & Segmentation
Sending the same email to everyone on your list is the fastest way to tank your deliverability and increase your unsubscribe rate. We manage and segment email lists for London businesses to ensure the right message reaches the right subscriber at exactly the right time.
Email Platform Management
Klaviyo. Mailchimp. HubSpot. ActiveCampaign. Brevo. We manage email campaigns across every major platform for London businesses — setting up properly, integrating with your existing tech stack, and ensuring every campaign is tracked and optimised correctly.
Email Performance & Reporting
Open rates. Click rates. Revenue generated. Deliverability. Every month, you’ll know exactly how your email marketing is performing — with honest reporting that shows what’s working and what we’re testing to make it better.

Which email marketing platforms do you manage?
We manage email campaigns across Klaviyo, Mailchimp, HubSpot, ActiveCampaign, and Brevo for London businesses. We can also migrate your list and setup from one platform to another if your current tool isn’t serving your business properly.
Do you write the email copy or do we need to provide it?
We write everything. Our in-house copywriting team creates subject lines, preview text, body copy, and CTAs for every campaign. You’ll approve content before it sends — we just need your brand voice guide, product information, and any campaign briefs you want us to follow.
What kind of results can I expect from email marketing?
Email marketing typically delivers £36 in revenue for every £1 spent when managed properly. For ecommerce brands, a well-built Klaviyo setup should generate 25-40% of total revenue from email. For B2B businesses, email is often the most effective lead nurturing channel available. We track all results back to revenue so you always know exactly what your email list is worth.
Can you build email automation and drip sequences?
Yes. Automation is one of our core specialities. We build welcome sequences, abandoned cart flows, post-purchase nurture, re-engagement campaigns, and behaviour-triggered drip sequences for London businesses. Once built, these campaigns generate revenue continuously without ongoing manual effort.
Do you offer email marketing for East London businesses?
Yes. We’re based in Royal Docks (E16), East London. We understand the East London business landscape and regularly work with businesses across East London, Canary Wharf, Stratford, Docklands, and Shoreditch. We’re one of the only email marketing agencies based locally in East London.
What's a good email open rate for a London business?
Average open rates vary by industry — B2B typically sees 20-30%, ecommerce 15-25%. With proper list hygiene, strong subject lines, and good segmentation, we regularly achieve open rates of 35-45%+ for our London clients. Open rate is one metric — click rate and revenue generated are the ones that actually matter.
