Email Marketing & CRM
For e-commerce brands, email is consistently 30–40% of revenue. It is also the most underbuilt channel in early-stage businesses — and the highest-return investment available once it is set up correctly.
What’s included.
Email is the only channel you own. Social platforms restrict your reach, paid media costs money every time, but your email list is an asset that compounds: every subscriber is a direct line to a customer or prospective customer that no algorithm can take from you. For e-commerce brands, a well-built Klaviyo infrastructure is consistently the highest-return marketing investment available.
OLUME builds the full Klaviyo infrastructure — welcome series, post-purchase flows, browse and cart abandonment, win-back sequences — and then runs the ongoing campaign calendar. The setup is built around your customer journey and your brand voice: every email looks and sounds like you, every flow is triggered by the right behaviour at the right moment.
Ongoing management includes A/B testing, list segmentation, list hygiene and monthly revenue reporting. We report on what email is actually contributing to your bottom line — not open rates and click rates in isolation, but attributed revenue by flow and campaign — so you have a clear picture of what is working and what the programme is worth.

Right for you if—
E-commerce brands whose email programme is underperforming, incomplete or non-existent. Founders who know that email should be generating a significant share of revenue but have not built the infrastructure to make it happen — either because Klaviyo felt complex or because there was never time to prioritise it over channels that felt more immediate.
Brands who have a list — accumulated through social, paid media or in-person events — but are not extracting the revenue from it. A list without flows and a campaign calendar is not an asset; it is an opportunity cost. And founders launching a new Klaviyo-powered Shopify store who want the email infrastructure built correctly at the point of launch, not retrofitted six months later.
The process.
01
Audit
Current email performance review, list health assessment, existing flow audit, Klaviyo account structure review. We establish what is currently generating revenue, what is missing and what the opportunity is.
02
Build
Klaviyo configuration, flow architecture, template design to brand identity, copywriting in brand voice. Every flow is built to the customer journey — triggering at the right moment with the right message.
03
Launch
Flow activation, list segmentation, first broadcast campaigns. We manage the launch carefully — warming lists that have been inactive, sequencing the activation of flows to avoid cannibalisation.
04
Optimise
A/B testing programme, list hygiene, ongoing campaign calendar and monthly revenue reporting. We optimise against attributed revenue — not vanity metrics — and refine the programme continuously based on what the data shows.
The competitive

Email marketing agencies typically offer Klaviyo setup or ongoing management as separate services — often through different teams — with a setup cost that does not include the ongoing expertise needed to actually run the programme. OLUME builds and runs the programme as a continuous engagement: the same team that designed your flow architecture manages your campaign calendar, so the ongoing programme is built on a real understanding of how your flows are performing and how your customers are behaving. And because we manage the brand identity and social creative for many of our clients, the email programme is coherent with the wider brand — not a separate aesthetic managed by a separate team.
