The starting point
One email every two weeks, and nothing automated
Earthing had no welcome series, no abandoned cart emails and nothing after a purchase. Every dollar from email depended on a campaign going out, and campaigns went out every other week.
The products are also new to most shoppers. Grounding needs explaining, so an email program that only sends discounts misses most of the people who sign up.

Open rate

What we did
Automations first, then a reason to sign up
01
Built four automated flows
Abandoned cart, window shopping (browse abandonment), a welcome series and post-purchase emails that drive repeat orders and ask for reviews. These run every day without anyone pressing send.
02
Added a spin-the-wheel sign-up module
An on-site wheel turned visitors into subscribers with first-purchase offers like 20% off, a free patch kit with an order or free Earthing slides. Daily sign-ups went from about 10 to more than 100.
03
Taught before selling
The welcome series answers what grounding is and where to start, with customer stories doing the convincing before any offer appears.
04
Kept campaigns on a calendar
Regular campaigns rotated launches, bundles and free-gift offers so subscribers had a reason to open without waiting for one big discount.
