Personalized Sticky Notes are a terrific marketing tool for anyone building a brand or wishing to build customer loyalty. This applies to both for-profit and non-profit organizations.
Otherwise known by the generic terms "Post-it Notes", sticky notes, sticky pads, adhesive pads, and others, they all have this in common: they give your brand constant exposure to your target market while offering a useful tool for the busy prospect. People make notes, and stick these sheets of paper on most anything.
When used thoughtfully (notice that I didn't say "properly"), a simple pad of sticky notes with your organization's logo, contact information, and tag line will give you 25 to 100 opportunities to remind your prospect of the value that you offer. There are no "proper" ways to use sticky notes, as what will work for one organization may not work at all for another.
