Typical engagement

How the weeks run.

WEEK 1

Email audit, customer journey, and lifecycle diagnosis

Sending reputation, list health and which lifecycle moments currently have no email at all.

WEEK 2

Flow strategy, segmentation, content, and automation design

The flows worth building, who they exclude, and the events the site has to send for them to work.

WEEKS 3–N

Campaign build, automation setup, template design, and testing

Built and tested against real segments, with tracking verified before anything is switched on.

FINAL WEEK

Reporting, optimization plan, and handover

Reporting your team reads without us, and a written plan for what to test next.

The honest read

How we approach email marketing systems

We use it when

  • There is a list with real purchase or usage history behind it.
  • Sending reputation is measurable, and someone cares what it is.
  • The site can emit the events flows trigger on, or can be made to.
  • There are lifecycle moments currently carrying no email at all.

We refuse it when

  • The list was bought, or its consent history cannot be established.
  • Volume is too low for behavioural flows to have anything to fire on.
  • The offer is what is failing, and email would only distribute it faster.
  • Broadcast sends are wanted while deliverability problems are already visible.
Deliverability and list health come before creative. Lifecycle flows based on behaviour come before broadcast campaigns. Attribution comes before optimization — we connect email sends to revenue before deciding what to test. Every engagement begins with an audit, not assumptions.
