Email Marketing Agency in the UK That Turns Subscribers Into Repeat Customers

We run email marketing on Klaviyo and Mailchimp for UK online shops and B2B businesses, with a focus on automated flows. Welcome series, abandoned cart, post-purchase and win-back emails go on bringing in revenue while you sleep. On top of that, we plan and design the campaigns, write the copy, keep your emails out of spam and report on the money email makes. We work with businesses in Milton Keynes, Bedford and Northampton, and across London, Manchester and Birmingham.

Common problems

Is Your Email List Making You Money?

Most businesses have a list. Very few are getting what they should from it. These are the usual reasons.

Illustration of a email marketing review showing the four problems on this page
  1. 01
    Campaigns

    You Send Newsletters but Sales Don’t Move

    A monthly round-up goes out, opens look fine, but nothing changes in the shop. The emails inform rather than sell.

  2. 02
    Automation

    You Have No Automated Flows Working While You Sleep

    No welcome series, no abandoned cart reminder, no thank-you or win-back. The emails that make the most money are not running at all.

  3. 03
    Deliverability

    Your Emails Land in Spam or Promotions

    Missing SPF, DKIM or DMARC records, old unengaged contacts and heavy images push your emails out of the main inbox.

  4. 04
    List growth

    Your List Isn’t Growing

    A sign-up box in the footer and nothing else. New subscribers trickle in while old ones lose interest.

Platforms

Klaviyo and Mailchimp Email Marketing

We work in the two platforms most UK businesses use. Klaviyo is our first choice for online shops: it connects closely with Shopify and WooCommerce, segments by what people buy and shows the revenue from every flow.

Mailchimp suits newsletters, service businesses and B2B lists that need simple campaigns, forms and tags. We set up, manage and migrate both, and will tell you honestly which one fits.
