Why Email & CRM Marketing Agency in London is different

London is one of the most sophisticated advertising markets in the world — and the least tolerant of boring, safe work. The creative bar is higher here than anywhere outside NYC. That shapes how we run email & CRM for every brand we work with London.

Media mix London has its own shape. Addressable TV (Sky, ITVX) is a serious media channel. Tube and OOH still drive brand outcomes. Podcast is the fastest-growing brand surface.

Email and SMS revenue engineered for the long run — deliverability-first, segmentation-heavy, and measured on incremental revenue, not open rates.

That is how we think about email & CRM. Ninety-day engagements, senior pods, a measurement model your CFO will sign off on, and a bias toward putting work in market over polishing decks.

What our email & CRM practice does

Across London, our email & CRM practice covers the full stack — strategy, production, channel management, and measurement — under one senior team.

  • Klaviyo, Braze, Customer.io, HubSpot
  • Lifecycle flow architecture
  • Segmentation and personalization
  • SMS and MMS campaigns
  • Deliverability and sender reputation
  • Zero-party data capture

Compounding CRM

Compounding CRM is how we run every email & CRM engagement London — the same method, tuned to your category and stage.

01 · Deliverability first — We audit sender reputation, warmup, authentication (SPF/DKIM/DMARC), and list hygiene. Revenue without inbox placement is a rounding error.

02 · Flow architecture — A 12-flow architecture (welcome, browse, abandon, post-purchase, winback, replenishment, etc.) with segmentation baked in.

03 · Campaign cadence — 2–4 campaigns per week, segmented, with a documented hypothesis per send. No "blast the list."

04 · Incremental measurement — Monthly holdout tests tell us what email actually incremental-drives versus what would have happened anyway.

What we measure

Every email & CRM program we run is measured on a short list of business KPIs. No vanity metrics.

  • Email/SMS-driven revenue %
  • Incremental revenue (holdout-tested)
  • Placement rate and inbox delivery
  • Active subscribers
  • Revenue per send

Who this is for

Our email & CRM practice is a fit for:

It is not the right fit for brands below $2M in annual marketing spend — for those we point to the self-serve side of Edison Moment at edisonmoment.com.

  • DTC brands with repeat-purchase categories
  • Subscription businesses
  • Hospitality and experiential brands
  • B2B SaaS with a lead nurture program

Why London brands choose us

  • Deliverability is a deliverable — not a support ticket.
  • Holdout testing tells us what's incremental — not every "email-attributed" dollar is real.
  • Segmentation beats automation — a 2-segment brand is leaving money on the table.
  • SMS is a sister channel, not an upsell — integrated from day one.
  • Weekly business reviews with a partner, not a status update from an account manager.
  • Creative production is in-house — not outsourced to a third-party studio you never meet.
  • Fee is at risk against a named KPI — typically 20–30% of the monthly retainer.

Frequently asked questions

Klaviyo, Braze, or something else?+

Klaviyo for ecommerce <$100M ARR. Braze for enterprise and mobile apps. Iterable and Customer.io for B2B SaaS. We pick by stack, not by affiliate.

What ROI should I expect from email?+

A healthy ecommerce brand sees 25–40% of revenue from email/SMS within 12 months. Below 15% is a big opportunity. Above 50% is a dependency risk.

Do you run SMS too?+

Yes, on the same team. Email and SMS share the lifecycle and segmentation architecture.

How do you handle deliverability drops?+

Monthly audits catch issues before Gmail or Yahoo tanks your sender reputation. If you've already been throttled, we have a 60-day recovery playbook.

Do you have a team on the ground London?+

EMEA office in Shoreditch, with a London-native strategy and creative team. The day-to-day cadence mixes live workshops with a UTC+0-aligned operating rhythm.

What makes a email & CRM program work London specifically?+

London is one of the most sophisticated advertising markets in the world — and the least tolerant of boring, safe work. The creative bar is higher here than anywhere outside NYC. Addressable TV (Sky, ITVX) is a serious media channel. Tube and OOH still drive brand outcomes. Podcast is the fastest-growing brand surface. We build the plan around those two things before we touch the channel mix.

How long until we see results?+

Ninety days to a working program. Six months to compounding returns. Twelve months to a email & CRM engine that doesn't need us to keep ticking. That arc is the same London as everywhere — but the first 90 days look different per market.
