Email and SMS marketing

Turn first-time buyers into loyal customers.

We build Klaviyo email and SMS programmes that bring customers back for a second, third and fourth order. You earn more from every customer you have already paid to acquire, without leaning on discount codes.

The short answerOn Digital is a Klaviyo partner agency for ecommerce brands. We build and optimise automated email and SMS flows, segment customers by behaviour and value, and run campaign calendars measured on repeat purchase and profit.

What you get

What a lifecycle programme gives you.

Flows do the heavy lifting, campaigns add energy, and both are measured on profit.

01

Revenue that arrives on autopilot

Welcome, browse, cart, post-purchase and winback flows earn every day without extra work from your team.

02

More repeat orders

Replenishment and cross-sell journeys bring customers back at exactly the right moment.

03

Healthier margins

Campaigns built around launches, stories and education, so you stop training customers to wait for a sale.

04

Messages people want to open

Segmentation by value and behaviour means every customer gets something relevant to them.

05

Emails that land in the inbox

Domain authentication and list hygiene keep your sends out of spam.

06

SMS that earns its place

Texts for high-intent moments like restocks and drops, and only where they add profit.

What we fix

Where email leaves money on the table.

The flows are set up once, the campaigns are all discounts, and nobody measures what email adds.

  1. Default flows, never improved. A welcome email and an abandoned cart flow set up at launch and untouched since.
  2. Every campaign is a sale. Customers learn to wait for a code, so margin drops with every send.
  3. Everyone gets everything. The same message to first-time buyers and loyal customers, and unsubscribes creep up.
Why it pays off

What loyal customers are worth.

Repeat customers cost nothing to acquire. Lifting repeat purchase is the most reliable way to grow lifetime value and make paid acquisition affordable.

  • Higher lifetime value per customer
  • Less reliance on discounting
  • Revenue that arrives while you sleep
  • Better return on every paid customer

Still deciding?

The questions brands ask us most before getting started.

Why use a Klaviyo agency?

A specialist agency builds flows and segments properly from the start, tests continuously and reports on profit. Most brands only use a fraction of what Klaviyo can do.

What email flows should every Shopify store have?

At minimum: welcome series, browse abandonment, cart and checkout abandonment, post-purchase, replenishment or cross-sell, and a winback flow for lapsed customers.

What percentage of revenue should come from email?

For established ecommerce brands, email and SMS commonly drive 20 to 35% of online revenue, with automated flows making up a large share. Where you sit depends on your category and purchase frequency.

Do we need SMS as well as email?

Not always. SMS works best for time-sensitive moments like drops, restocks and delivery updates. We only recommend it where it adds profit after costs.
