Shelter's direct mail campaign aims to explain that one of the charity's highest priorities is to offer support to people whose lives and health are at risk through bad housing.
Around 90,000 people are being sent a leaflet based on two case studies.
One features a young student who has died from carbon monoxide gas emitted from a faulty gas fire. The other shows a single mother on housing benefits concerned because her landlady will not fix her fire. She turned to Shelter who intervened and helped the family to get re-housed.
"Over 570,000 households in England live in poor quality rented accommodation and the case featured in this direct mail pack demonstrates the terrible conditions that many people have to endure,
said Alan Gosschalk, fundraising director at Shelter.
The campaign aims to motivate people to become regular supporters of Shelter and asks for a gift of £15 to allow the charity to continue its work
A press campaign called Home Sick was also launched to highlight the affects of bad housing on health.
The campaign also highlights a Private Member's Bill being supported by Shelter. The Bill, which is currently half-way through parliament, intends to force some of the most dangerous and unhealthy shared private housing to be licensed.
