YOUR ENGINE, MAPPED FROM YOUR DIAGNOSTIC BEFORE WITH EVERBOOST

"Our programme has improved significantly since working with them. Retention has improved, our subscribers are more engaged, and we're seeing real commercial impact from the channel."

Adam Oxley · Co-Owner, Discount Supplements

You've seen "free audit" before

Every agency offers an audit. Most of them are one of these.

If an audit doesn't change what you do next Monday, it wasn't an audit. Here's what a real one contains.

The deliverables

What the audit contains.

01

The data

Your account, dug into properly

We go through Klaviyo, Shopify and your subscription platform the way we would for a paying client, alongside the context from your intro call. Real access, real depth. No dashboard skim.

02

Lifecycle review

Every flow and campaign, reviewed

What's working, what's underperforming and what's missing entirely, judged against the brands like yours we run every day, with the revenue at stake attached to each gap.

03

The levers

Your growth levers, ranked

Where your repeat revenue actually comes from, and the levers that grow it: more first-time buyers coming back for a second order, subscription sign-ups, churn saves, win-backs. Ranked by what each one is worth to you.

04

The plan

A plan you could run yourselves

A prioritised roadmap: what to fix, kill and build, in what order, and what each step is for. Detailed enough that your own team could execute it without us.

Built from your account, your customers and your numbers. Never a template.

Sneak peek

See it before you request it.

A page from the diagnostic, rebuilt with sample data. Yours uses your real numbers, and real numbers are less polite.

For subscription brands

Run subscriptions? The audit opens up the engine.

Subscription revenue is decided by nine numbers across three systems: how subscribers join, how they leave, and what each one is worth while they stay. The diagnostic measures all nine and shows you which is costing you most.

Fig. 02 · the subscription layer of the retention engine

System 01 · Intake

Subscribers joining

  • 01% of new orders that start on subscription
  • 02% of one-time buyers converted to subscription
  • 03% of churned subscribers won back

System 02 · Leaks

Subscribers lost

  • 04Voluntary cancellation %
  • 05Failed-payment churn %
  • 06Cancellations before the first renewal

System 03 · Output

Value per subscriber

  • 07Subscription first-order value
  • 08Recurring order value
  • 09Orders per subscriber

No subscription programme? The same rigour goes into repeat purchase: getting more first-time buyers back for a second order, and growing the repeat revenue behind it.

What the plan turns into

Every engagement starts with this exact audit. Then this happens.

Every number below is verified client data from a full case study on this site.

★★★★★

"Will they go quiet after month one?"

"Every week, without fail, there's an update in our inbox. No chasing, no wondering what's happening, it just arrives."

Adam Oxley Adam Oxley · Co-Owner, Discount Supplements

★★★★★

"Is this just email?"

"Everboost go beyond email to consider retention improvement across the board. I couldn't recommend them more."

Pia Winberg Pia Winberg · Founder, PhycoHealth

★★★★★

"Do the results actually come?"

"We saw a 20% increase in revenue in just three months. The best part has been the consistent communication and detailed feedback we receive."

How it works

From intro call to plan in about a week.

01

Book an intro call

Thirty minutes, consultative. We hear the story behind your numbers, you hear exactly how the audit works, and we decide together whether it's worth running. If the honest answer is that you don't need us yet, you'll hear that too.

02

Share access

Manager access to Klaviyo and your subscription platform, plus Shopify. Deep access is what separates a real audit from a dashboard skim: it lets us dig into flows, segments and customer data properly. About fifteen minutes of your time to set up.

03

The diagnostic lands

Within about a week: the findings, the lifecycle review and the prioritised plan, walked through together so every recommendation arrives with a number and a reason attached.

04

You decide

The plan is yours to keep either way. If you're open to working together, we'll put a proposal in front of you on a follow-up call, and we'll be upfront about that from the start.

We build a handful of diagnostics a month alongside client work. If the calendar is full, you get the next slot, not a rushed audit.

Fair questions

Asked by founders like you.

Is it actually free, or a pitch in disguise?

It's free, and it's the same diagnostic every Everboost engagement starts with, so we build it properly regardless of what happens next. We're upfront about the commercial side on the intro call: if you're open to it, we'll put together a proposal and present it on a follow-up call. If you're not ready for that conversation, the plan is still yours to keep.

What do you need from us?

Manager access to Klaviyo, Shopify and your subscription platform (Loop, Skio, Recharge or similar), plus a short intro call for context. Deep access is what makes the audit genuinely useful: it lets us dig into the data properly instead of reading the same dashboards you already look at. About fifteen minutes of your time to set up.

How long does it take?

About a week from access to walkthrough. We build a handful of these a month alongside client work, so slots are subject to availability. If the calendar's full, you get the next slot rather than a rushed audit.

What if we don't want to work with you afterwards?

The plan is yours and there's no obligation. We'll be honest about why the audit is free: brands who see exactly where their revenue is leaking usually want the team that found the leaks to fix them. If the timing isn't right for you, we'll check back in further down the line, and that's as pushy as it gets.

Who actually builds it?

A senior strategist on the Everboost delivery team. Not a junior with a checklist, not a template with your logo on it. Every audit is built from your live data, from scratch.

Do we need to run subscriptions?

No. If you run a subscription programme the audit goes deeper into the nine numbers above. If you don't, the same rigour goes into repeat purchase: getting more first-time buyers back for a second order, and growing the repeat revenue behind it.

Where to start

Your numbers already know where the leaks are.

Book the intro call. If the audit is worth running, you'll have a prioritised plan inside a couple of weeks: what to fix, kill and build, in order.
