Marketing automation

Email marketing automation for UK businesses

Stop blasting the same newsletter to everyone. We build the lifecycle email engine that sends the right message to the right person automatically — and lands it in the inbox, not spam.

Where email programmes leak value

You're sending one email to everyone and calling it a strategy.

Most UK businesses with an email list do two things: an occasional newsletter to the whole database, and a single automated welcome email nobody's looked at since it was set up. The platform can run a dozen behaviour-triggered flows that quietly generate revenue every day. Instead it generates one open-rate number that slowly declines.

  • One list, one message — Everyone gets the same email regardless of where they are in their journey. New subscribers, loyal customers and people who haven't engaged in two years all receive identical content. Relevance — and revenue — leaks away.
  • Flows that were set up once — A welcome email exists. Maybe an abandoned-cart flow. They were built at launch and never revisited. The re-engagement, nurture, win-back and post-purchase flows that drive most automated revenue were never built at all.
  • Landing in spam — No DMARC record, a shared sending domain, and a habit of mailing contacts who haven't opened in a year. Deliverability quietly collapses. Half your emails never reach the inbox and nobody knows why the numbers dropped.
How we think about it

Flows that earn, not emails that get sent.

Email automation isn't about volume. A good lifecycle programme might send each contact fewer emails than a weekly blast — but every one is triggered by something they did and relevant to where they are. We design the lifecycle and the deliverability foundation before we build a single flow.

  • Independent — no platform commissions — We're not a Klaviyo, HubSpot or ActiveCampaign partner. We earn nothing on your subscription, so we recommend the right platform for your model rather than the one that pays us.
  • Deliverability first — There's no point building beautiful flows that land in spam. We set up SPF, DKIM and DMARC, a dedicated sending subdomain and engagement-based sending before we optimise anything else.
  • Built to be owned — Every flow ships with documentation your marketing team can extend. We build the engine and hand it over — we're not locking you into a retainer to press send.
The email flows we build most often

Seven flows that quietly generate revenue.

These are the lifecycle flows almost every UK business should have running. Most programmes we inherit have one or two; we build the rest.

Welcome & onboarding
A multi-step series that introduces new subscribers or customers, sets expectations, delivers the lead magnet they signed up for, and moves them toward a first or second purchase. The highest-engagement emails you'll ever send — and usually the most under-built.
Nurture sequences
Educational, behaviour-branched sequences that move a lead toward a buying decision. Content tailored to the segment, with branches based on what they click and engage with. The backbone of B2B email — see B2B marketing automation.
Re-engagement & win-back
When a contact goes quiet, an automated sequence tries to win them back — and if it fails, suppresses them to protect deliverability. Cleaning your active list automatically instead of mailing dead contacts forever.
Segmentation architecture
Dynamic segments built on real behaviour, lifecycle stage and purchase history — so every flow targets the right people. The difference between 'email everyone' and 'right message, right person'.
Dynamic content & personalisation
One email that renders differently for different recipients — product recommendations, location, lifecycle stage, last purchase. Personalisation that scales without building a hundred separate emails.
Deliverability & consent
SPF, DKIM, DMARC, a dedicated sending subdomain, list hygiene, domain warm-up, and GDPR/PECR-compliant consent capture with a logged audit trail and a working preference centre.
Reporting & attribution
Closed-loop reporting that ties each flow to revenue, not just opens and clicks. Which flow earns what, so you know where to invest next.
How we deliver

A four-phase engagement, priced flat

No hourly billing. No scope creep. You know what you're paying and what you're getting before we start.

1
1. Discovery (1 week)

We audit your current flows, list health, segmentation, deliverability and consent setup. We map your customer lifecycle and find the missing and misfiring flows. Output: a prioritised build list with predicted revenue impact.

2
2. Strategy (3 days)

We pick the highest-ROI flows to build first, in order. You see the business case for each before signing off. If your platform is wrong for your model, we say so here.

3
3. Build (2–5 weeks)

We fix deliverability first, then build the flows, segments and dynamic content alongside your marketing lead. We test against real data and a seed list before going live.

4. Handover & 90-day review

Documentation, training and a check-in 90 days after launch to measure revenue per flow. After that, fractional CAO retainer or done — your call.

What email marketing automation actually means

Email marketing automation means sending emails triggered by behaviour and lifecycle stage rather than by a person clicking 'send'. Instead of one newsletter to your whole list, you have a set of automated flows: a welcome series that fires when someone subscribes, a nurture sequence when they download a guide, a re-engagement flow when they go quiet, a post-purchase series when they buy. Each one is personalised to the recipient and runs automatically, forever, without anyone touching it.

The three building blocks are simple:

  • Flows — multi-step automated sequences (welcome, nurture, win-back, post-purchase).
  • Segments — dynamic groups defined by behaviour, lifecycle stage or purchase history.
  • Triggers — the events that start a flow (subscribe, download, abandon, purchase, go quiet).

Get those three right and your email programme stops being a weekly chore and becomes an engine that generates revenue in the background.

The flows almost every UK business should have

In order of how reliably they pay back:

Welcome and onboarding

The most-opened emails you'll ever send, because the recipient just chose to hear from you. A good welcome series introduces the brand, delivers whatever they signed up for, sets expectations and moves them toward a first or second purchase. Most businesses have a single welcome email; the revenue is in the three-to-five-step series.

Nurture sequences

For B2B especially, this is the core. A captured lead enters an educational sequence that branches based on what they engage with, gradually moving them toward a sales conversation. The B2B marketing automation page covers the lead-scoring and sales-handoff side in depth.

Re-engagement and win-back

When a contact stops opening, an automated sequence tries to win them back — a 'we miss you', an incentive, a 'is this goodbye?'. If it fails, the contact gets suppressed automatically. This does double duty: it recovers some lapsed contacts and protects your deliverability by stopping you mailing dead addresses.

Post-purchase and retention

For ecommerce this is where most automated revenue lives — order confirmation, shipping, review request, replenishment reminder, cross-sell, win-back. The ecommerce marketing automation page covers the full ecommerce flow set.

Deliverability: the foundation everyone skips

There is no point building beautiful flows if they land in spam. Deliverability is the unglamorous foundation, and it's where most of the email programmes we inherit are quietly broken.

The essentials:

  • Authentication. SPF, DKIM and DMARC records set up correctly for your sending domain. DMARC in particular is now effectively mandatory — Google and Yahoo require it for bulk senders since 2024. Most broken programmes are missing it.
  • Dedicated sending subdomain. Marketing email should send from a subdomain (e.g. mail.yourbrand.co.uk) so a deliverability problem with marketing doesn't poison your transactional and corporate email reputation.
  • List hygiene. Suppress hard bounces immediately and chronic non-openers progressively. Mailing dead contacts is the fastest way to destroy sender reputation.
  • Domain warm-up. A new sending domain has no reputation. Ramping volume gradually over a few weeks builds trust with the mailbox providers.
  • Engagement-based sending. Mail your engaged segment more and your dormant segment less. Mailbox providers watch engagement closely; sending to people who never open drags everyone's deliverability down.
  • Monitoring. Google Postmaster Tools and your platform's deliverability dashboard to catch reputation drops before they become disasters.

GDPR, PECR and UK consent

UK email marketing is governed by UK GDPR and PECR (the Privacy and Electronic Communications Regulations). For marketing email to individuals you generally need consent, with a 'soft opt-in' exemption for existing customers being marketed similar products. We build:

  • Granular consent capture — clear, specific opt-in at the point of collection, with the purpose stated.
  • A logged audit trail — when consent was given, how, and for what. If the ICO ever asks, you can prove it.
  • A preference centre — so recipients can choose what they receive rather than only being able to unsubscribe from everything.
  • Instant suppression — unsubscribes and consent withdrawals honoured immediately across every flow, not just the one they unsubscribed from.

Platform choice

For email automation specifically, the patterns for UK businesses:

  • Klaviyo — the default for ecommerce. Built around purchase behaviour, deep Shopify and WooCommerce integration.
  • ActiveCampaign — excellent value for B2B and considered-purchase B2C. Strong automation builder without the full CRM cost.
  • HubSpot — when email is part of a wider CRM and sales motion. See HubSpot consultants.
  • Customer.io — for product-led businesses needing event-driven, behavioural messaging across email and other channels.
  • Brevo / MailerLite / Mailchimp — for smaller businesses where simplicity and cost matter most.

We size this in discovery and are equally happy improving the platform you already have.

What does it cost?

  • Core lifecycle flow build (welcome, nurture, re-engagement): £4k–£8k.
  • Full programme with segmentation, dynamic content, deliverability and reporting: £8k–£15k.
  • Full lifecycle architecture across acquisition, conversion and retention: £15k–£25k.

Fractional CAO retainer afterwards: £5k–£15k per month. We bill flat fees, never hourly, and take no platform commissions. To scope first, the £1,500 Discovery Sprint audits your programme and gives you a costed build plan.

When email automation isn't worth it

  • A small, static list. Under a few thousand engaged contacts with no growth — grow the list first.
  • Messy data. No clean segmentation fields means automation just personalises badly at scale. Fix the data first.
  • Nothing to say. No content, offers or lifecycle worth nurturing — automation sends empty flows faster.
