Earn More from the Customers You Already Have

Email is the channel you own, and for most ecommerce brands it is one of the biggest. Across 198 client stores, email is a median 30% of revenue.

Every engagement starts with an audit of your Klaviyo account: flows, segments, campaigns, forms and deliverability. It shows which flows are missing, where revenue is leaking and what to fix first.

Why Ecommerce Email Needs a Specialist

Ecommerce email is not a newsletter. It is a system of automated flows, campaigns and segments running on your Shopify data, and small gaps in it cost sales every day.

Klaviyo's Shopify integration passes customers, orders, products and browsing into your account, so flows can trigger from real shopping events. We build on that data rather than sending the same email to everyone.

Why Matters is a Klaviyo partner and a Shopify Select partner. Mama Bamboo credits our work with cutting subscription churn by 23% within three months and lifting subscription lifetime value by 45% within five.

How Our Email Management Works

We manage email to revenue and retention, not open rates. Before changing anything, we agree the numbers that matter: email's share of revenue, repeat purchase rate and list growth.

We then fix the essential flows, build segments, plan campaigns a month ahead and test subject lines, content and timing every week. Each month you get a report on revenue, list health and what we will do next.

For the numbers worth comparing against, see our guide to benchmarking your Shopify email revenue.

Automated Flows Built on Shopify Data

Flows send the right email at the right moment without anyone pressing send. Across our Klaviyo clients, the welcome series and abandoned cart and checkout flows are normally the best performers.

Yet 37 of the last 50 startup stores we took on had no welcome flow live. We build the essential flows first, then add browse abandonment, post purchase, replenishment and winback as the data supports them.

Selling subscriptions? Our Shopify subscriptions service and our guide to the Klaviyo flows every subscription brand should build go further.

Campaigns and Segmentation

Campaigns turn launches, restocks and seasonal moments into sales. We plan them a month ahead, write and design them for phones, and send them to segments rather than the whole list.

Segments built from purchase history, product interest and engagement bring fewer unsubscribes and more revenue per email. Sending less often to people who never open also protects your deliverability.

SMS Marketing with Klaviyo

SMS reaches customers fast, which makes it right for a few moments and wrong for most. We use it for launches, back in stock alerts and abandoned baskets, alongside email rather than instead of it.

UK marketing texts follow the same PECR rules as marketing emails: consent, or for existing customers buying similar products, a clear chance to opt out. We set up sign up forms and consent records that meet them.

Deliverability and Inbox Placement

The best email earns nothing in a spam folder. Since February 2024, Gmail has required anyone sending over 5,000 emails a day to authenticate their domain, offer one click unsubscribe and keep spam complaints below 0.3%.

We check SPF, DKIM and DMARC, send from your own domain, clean out subscribers who never engage and watch complaint rates. Our guide to stopping Shopify emails landing in spam covers the detail.

Sign Up Forms and List Growth

Email revenue depends on who joins the list. We design sign up forms that grow it with people likely to buy, without interrupting everyone else.

Incentives need care, because a discount brings sign ups but can teach people to wait for codes. An organic cosmetics client of ours grew its list from 67 to 298 subscribers in three months.

See our guide to getting more email subscribers on your Shopify store.

Frequently Asked Questions

How much does an email marketing agency cost?

Most agencies charge a monthly retainer, sometimes with a setup fee for building flows, while your Klaviyo subscription is paid to Klaviyo. We quote after the account review, based on your list and the work involved. Retainer clients are billed one month in arrears and never tied into long contracts, and our Shopify packages show how we price our work.

Why use Klaviyo with Shopify?

Its Shopify integration passes customers, orders, products and browsing into Klaviyo, so flows and segments run on real shopping behaviour. That depth is why we recommend it for most growing Shopify brands, and we are a Klaviyo partner.

How much revenue should email bring in?

Across 198 client stores, email is a median 30% of revenue. Your figure depends on your list, your flows and how attribution is set, and our email benchmarks guide explains what to compare against.

Which email flows should a Shopify store set up first?

Welcome, abandoned cart, abandoned checkout and post purchase. Across our Klaviyo clients, the welcome series and abandoned cart and checkout flows are normally the best performers.

Can you fix emails going to spam?

Usually, yes. Most problems come from missing authentication, sending from a shared domain or mailing people who never open, and each has a clear fix.

Do you also run SMS?

Yes, through Klaviyo. We use SMS for a few high value moments alongside email, with sign up and consent handled under the UK's PECR rules.
