We will get you better results by;
1. Actually delivering your products
2. Don't deliver competing industries together
3. Size matters! All letterboxes can cater for DL and A5 but larger is not guaranteed. Ensuring the products don't exceed A5 in overall size will already get you better results
4. Put products IN the letterbox NOT on the box
5. Don't roll, rubberband or fold brochures inside each other
6. Colour and design matters.
8. Knowing the delivery laws.
9. Keeping accurate counts on households
10. Delivering each week of the month on a monthly cycle, no wasted excess marketing only benefitting the deliverer, not you.
