If you think that printing ten thousand flyers and distributing them through letterboxes is going to work, then you're probably wrong or at least, there's room for improvement. Consumers are bombarded with advertising and want to make their own choices rather than be sold to. If you do however want to push your message onto customers then you need to be appealing, relevant and a little different to all of the other advertisements received that day.
Imagine if your flyer could turn up, at the very moment that your prospect needed your service.
Imagine if you were the brand they always thought of first.
Imagine if every time your advertisement was distributed, it was only ever delivered to people that could or wanted to buy.
