We are a small charity who have already processed a direct mail campaign to warm donors with a high return rate. We are now considering a cold mail leaflet door drop with the Royal Mail for our new campaign and wondered if anyone could give some feedback on this. The leaflet drop will be to around 190,000 in our local catchment area including businesses. Any feedback would be very much appreiciated as we are very apprehensive regarding cold mail, due to cost implications etc
