Want a simple way to double the chance somebody will respond to your letter or request? Then capitalize on the fact that people need to feel they are getting personal attention. In several tests (neurosciencemarketing.com), it was found that when a handwritten, yellow sticky note was attached to a letter or advertisement… the response rate more than doubled.
Here’s the odd thing… handwriting the note ON the actual letter or advertisement did boost response… but only by 50%. Handwriting the exact same note on a yellow sticky note affixed to the letter boosted response by 100%. And it gets better… the responses with the sticky were also more thorough and prompt!
