Email marketing for Bulb (2019-20)

The brief

As Senior Copywriter at Bulb, I wrote emails marketing new products to Bulb customers, as well as comms informing them about their account.

This particular marketing email announced Bulb’s new carbon calculator to over 1.7 million customers, so they could work out and offset their carbon footprint.


I worked with the product team to understand the product’s key offer, and what benefits it could give Bulb customers.

The process


The outcome

Subject: <Offset your carbon footprint >

Heading: Offset your footprint from £5 a month 

Hi *|FNAME|*,

Bulb helps you manage carbon emissions at home. Now we’d like to help you manage them everywhere. 

Answer a few simple questions about the way you normally get around, the food you eat, and the things you buy. You’ll go from green hero to carbon zero in no time.

Your money will go towards projects dedicated to cutting the planet’s CO2 levels. 

So you’ll be helping protect the Gola rainforest in Sierra Leone, provide clean cookstoves in Ghana and Kenya, and support wind and solar energy in India.

Offsetting really works

Our projects are verified by the Gold Standard and Verified Carbon Standard in partnership with ClimateCare. So you can be sure your money gives the planet a well-earned breather.

You’ll be part of something big

Every month at Bulb we offset over 250,000 tonnes of CO2. It’d take 125 million trees to absorb that much in a year. 

 Happy offsetting,

Team Bulb
