Many individuals running direct mail campaigns will throw in a ‘free gift’ to tempt an increase in conversions. You may be attempting to attract more email subscriptions, or followers on Facebook, or perhaps sales and throwing in a free gift can certainly help.

A gardening company may want to boost sales for various gardening products by including free bulbs, while a simple gift like a key ring can ensure your customers have your relevant contact information at their disposal for future purchases.
The gift should always be branded, otherwise you may not get the recognition you deserve. A free gift does go a long way, as long as it’s connected to your business and their products/services. Try it yourself for a week or two; you may then see a sudden rise increase in conversions.
