You can buy a stack of paper for post cards but if you don't have a really great marketing message that's proven to perform over and over... that paper won't do anything for you. 

Good Afternoon Investor/Wholeselers,Just had a few questions for your guys, I send anywhere between 5,000-8,000 postcards a month.I dont know exactly the response rate, but I do get tons of calls from my campaigns, but deals have drastically slowed down since a year ago.

You can even buy postcards that go right into your printer to save your hands from hand-jamming them yourself.

Currently, I am mailing letters, and I've sent out postcards in addition to driving for dollars.

Since we implemented this feature in our postcard funnel our response rates more than doubled.Many sellers may be interested in learning more about what you can do for them, but are reluctant to call.

The use of direct mail advertisements cal also help you if you can afford to send out hand-written post cards that are over-sized to grab their attention.  

Get a list and send them a yellow post card.

You'll need to be doing 1) google ads, 2) Facebook ads, 3) letters and post cards, and 4) answer your phone.

When you do get a Property under contract, Look up on MLS or other sites all cash buyers who have bought around that property in last 6 months and send them a flyer or a postcard of you, your featured property and about your company.4.

You have a much better chance of connecting with an owner if you are persistent rather then doing mass mailings hoping to hit that one owner who is ready to sell at the exact moment they received your post card.
