The problem
Most ecom brands send a few emails. Very few have a lifecycle engine.
If email is doing 10–20% of your revenue, you're leaving real money on the table.
The difference isn't sending more emails. It's sending the right message to the right person at the right time.
And with paid acquisition costs climbing every quarter, the brands without a lifecycle engine are the ones getting squeezed first. You can't out-spend rising CAC. You can out-retain it.
Without a lifecycle engine
- Short-term revenue thinking
- Discount-heavy months
- Low repeat purchase
- Expensive paid acquisition
With a lifecycle engine
- 30–50% email contribution
- Higher customer LTV
- Predictable monthly revenue
- Paid ads finally profitable
Why us
Most agencies say the same things. Here's how we're actually different.
Typical Klaviyo agency
- Junior account managers do the work
- Set-and-forget flows
- Sends the same campaign to your whole list
- Reports open rates and "attributed revenue"
- Pulls flows from a template library
- Sells you on retainer length
Inevitable Marketing
- Senior strategists do the actual work
- Weekly testing and optimisation
- Segments by behaviour, intent, and purchase history
- Reports % of total revenue, LTV, repeat purchase rate
- Builds flows around YOUR brand and YOUR data
- Stands by what we promise — delivers results
And here's what we won't do.
- We won't optimise for vanity metrics like open rates or Klaviyo's "attributed revenue."
- We won't pull flows from a template library and slap your logo on them.
- We won't sell you on retainer length. We sell on results — and we stand by them.
- We won't lock you in to long-term contracts. We prove ourselves, and you decide how long you keep us around.
How we do it
A 3-phase rebuild of your retention engine.
→ First quick wins in 30 days. Real, measurable lift by 60.
Diagnose.
We pull apart your current setup — flows, segmentation, creative, reporting. We map where revenue is leaking and where the easy wins live. No assumptions, no guesswork.
Build.
We rebuild Klaviyo around behavior-driven flows: welcome, browse, cart, post-purchase, win-back, VIP, churn recovery. Designed to your brand — not pulled from a template library.
Improve.
Consistent testing, optimisation, and reporting. Email becomes your most reliable asset.

What our clients actually say:
"Quality of their output is great. We are continually leveraging them more and more to help grow our business."

Sample work
Real emails we've shipped.
Welcome flows, campaign heroes, seasonal sends — twelve emails we've shipped, across ten brands.
The metric reframe
Most agencies are optimising for the wrong thing.
If your only measure of email success is Klaviyo's "attributed revenue" number, you're missing the picture. Anyone can game that number.
What we actually measure — and what you should:
- % of total monthly revenue from email (target: 30–50%)
- Customer LTV — are your buyers worth more over time?
- Repeat purchase rate — are you actually retaining anyone?
- Discount dependency — are sales coming from real demand or constant promos?
If your current agency can't tell you these numbers, they don't understand retention. They're just sending emails.
Testimonials
What our clients say — unprompted.
★★★★★ Rated Excellent on Trustpilot"Mac and team are incredible. Have loved working with them. Quality of their output is great. Costs are reasonable. We are continually leveraging them more and more to help grow our business."
"Mac and the team have been amazing. I was just randomly sending emails before but they came in and set up my flows. Now we are sending weekly emails and engaging with my clients. The emails bring in lots of sales. I referred them to another friend who has a Shopify store and he loves them too."
"Mac and his team are amazing! Of course they're making us money and improving our metrics like we love, but they're also so easy to work with. We're a small business so sometimes things are chaotic and unorganized on our end, but they work with us and make email marketing effortless for us!"

Common questions.
How long until we see results?
Quick wins typically land in the first 30 days. Measurable lift usually follows within 60 days. We're not here to drag this out — we're here to make email a real revenue line.
How much of your time do we need?
Most brands spend 30–60 minutes per week reviewing and approving work. We do the heavy lifting; you keep the final say.
Do you guarantee results?
We guarantee results when our pre-evaluation shows the data is there to support them. If your fundamentals aren't ready, we'll tell you straight — not sell you something that won't work.
What does it cost?
Engagements start at £1,500/month, scaled up from there based on your revenue, lifecycle complexity, and scope. Month-to-month — no long-term contracts. We'll dial in the exact number on the strategy call once we've seen what your account actually needs.
Do we have to use Klaviyo?
Klaviyo is where we do our best work and where most 7–8 figure brands land. If you're on another platform, we can discuss it on the call.
