Klaviyo or Mailchimp?

Commerce-heavy usually Klaviyo. Simpler lists can live in Mailchimp. CRM-led teams often stay in HubSpot. We pick for the stack you have.

Can you write the emails?

Yes. Copy and templates. Voice still needs a brand owner.

Do you chase open rates?

Open rate is a vanity metric we will not worship. Clicks and revenue or MQLs matter more, especially with privacy changes.

How do you handle GDPR / PECR?

Consent and unsub are non-negotiable. We will not blast a scraped list.

How fast can flows go live?

Priority flows can be weeks if the tool and data are ready. Hygiene first if the list is dirty.

If scoped. Different consent rules.

Can you take over a messy account?

Yes, after a hygiene and auth audit.

Will you fix deliverability?

SPF/DKIM/DMARC, list quality and sunset. If you are already in spam, we start there — not a big send.

Can you migrate ESPs?

Yes, without wrecking consent history.

What does email marketing cost in London?

Depends on ESP, list size and flow count. Share the journey (ecommerce vs services) for a proposal.

Do you offer retainers?

Yes. Campaigns and flow iteration are ongoing.

Lifecycle email, not a Thursday panic send

Email built as a system: capture, flows, campaigns

Design Dev implements email as lifecycle: capture, welcome, abandon, replenish, winback and campaigns. We nurture stronger customer relationships with targeted email — from personalised journeys to automation — and we care about consent, deliverability and a CRM that is not a graveyard of unmailable addresses.Klaviyo, Mailchimp or HubSpot: the tool you already have, set up properly. DNS (SPF/DKIM/DMARC) and flows before a “big send”.

Lifecycle Flows

Welcome, abandon, post-purchase, nurture and winback — mapped to the journey.

Campaigns with a Reason

Not “we should send something on Thursday”. Design and copy that match the offer.

Klaviyo, Mailchimp, HubSpot

Commerce-heavy usually Klaviyo. CRM-led teams on HubSpot. Simpler lists can live elsewhere.

Deliverability & Hygiene

Auth records, list quality, sunset policies — or you are shouting into spam.

Our email process — from list truth to lifecycle live

Audit the Stack

Tool, DNS auth, list quality, current flows and consent. Hygiene before volume.

Journey Map

What email should do vs WhatsApp vs ads. Priority 2–3 flows that move money or leads.

Build Flows & Templates

Welcome to winback. Mobile, dark mode, actual buttons. Accessible templates.

Campaign Rhythm

A calendar you can staff. A/B on the expensive sends. Landing match.

Measure

Revenue or MQLs per flow — not open-rate theatre, especially with privacy changes.

Email is still high-ROI when the list is real

A bought list is not a strategy. Consent and relevance are how you stay out of spam and out of trouble under GDPR/PECR. Design Dev will fix DNS and flows before a big send.We will not blast a scraped list. Unsub is non-negotiable. No dark patterns.
