A collective of charities is using email to promote an environmental fundraising campaign.
The email drive is part of the "Health Matters" appeal run by Breast Cancer Campaign, the Multiple Sclerosis Society, the Prostate Cancer Charity and the Stroke Association alongside electronic retailers the Dixons Group.
Supporters and Dixons' employees will receive an email asking them to order a freepost envelope and then send in their used computer inkjet cartridges to be recycled. Dixons will give a donation for every cartridge received.
The charities hope to raise a "significant" percentage of the £100,000 campaign target through the online campaign.
"When the recipient opens the email it will take them no more than one minute to order their free recycling envelopes," said Joanne Dunsford, corporate fundraiser at the Stroke Association.
The email also includes a competition to win a Microsoft X-Box supplied by Dixons.
