Mass Mail Marketing - What works?

[Lisa Beard]

I am just starting to manage other vacation rental properties in my area, and have a targeted list of owners I would like to reach out to. What have you found that works best in trying to gain additional business (or even getting someone to sell off market)? A few ideas I have heard are handwritten addresses (which would take forever, but I'm open), including something like a keychain or koozie with your logo, personalized letter, etc. Any ideas? Approximate lead conversion rates? Thank you!
