Strategy, copy and sending

Campaigns and flows built in Klaviyo or Mailchimp and shaped around how your customers actually behave.

✓Lifecycle flows: welcome, cart, post-purchase, winback

✓Campaigns for launches, sales and newsletters

✓Copywriting in your brand voice

✓Responsive template build, slicing and QA

✓A/B testing and monthly reporting

List growth

Grow a list that buys

More subscribers is only useful if they are the right ones. We set up sign-up points and segments that keep your list healthy.

✓Pop-ups and embedded forms

✓Segmentation by behavior and interest

✓List cleaning and sunset flows

Design

Creative that holds the brand together

Emails are one touchpoint. We design the creative around them so every surface looks like one company.

✓Email and landing page visuals

✓Social media creatives

✓Meta ad creatives

✓Short-form video editing
