UK dog-supplement brand

An email program built from almost nothing: £76,149 in nine months.

£76,149Email and SMS revenue · April–December 2025 · £683 a month before

Before we started, email and SMS brought this dog-supplement brand about £683 a month. Over the next nine months we sent 80 campaigns, tested every flow and grew the list, and the channel brought in £76,149. December 2025 alone was £18,300. The brand is not named here.

The brief.

The brand had a list and a Klaviyo account and was sending almost nothing. In the eight months before we started, email and SMS averaged £683 a month, and March 2025 had no campaigns at all.

Our approach.

We started a weekly campaign calendar, tested the signup forms to grow the list, and put a subject-line or layout test on every flow email. SMS joined in June.

The results.

Klaviyo-attributed email and SMS revenue by calendar month, in pounds, from our month-by-month record for the account. The eight months before April 2025 are the starting point. There is no store-revenue figure in the record, so no share of sales is claimed.

What we did.

The main pieces of work on this account.

A campaign calendar from a standing start
Six to eleven campaigns a month from April 2025, where March had none. Revenue per campaign recipient rose from £0.04 in January to £0.25 by November and December.
Signup forms tested to grow the list
Mobile and desktop popups were tested on offer and layout. A surprise offer converted 11.38% of mobile visitors against 8.23% for a stated 10% off, in one test of about 1,800 views.
Flows tested email by email
Welcome, abandoned checkout, abandoned cart, post-purchase and winback flows, with subject-line and layout tests. The winning welcome subject line earned £1,430 from 405 recipients against £609 from 263.
SMS alongside email
Three SMS campaigns and SMS flows from June 2025.

Sources and limits

Much of the increase comes from a larger list. Campaign recipients rose from 2,771 in December 2024 to 43,862 in December 2025, so this is a program built out, not the same list earning more.
There is no store revenue in the record, so email’s share of sales is not known.
The start of the engagement is taken from the first dated test, April 13, 2025.
The brand is not named, and its creative is not shown.
