@Ana G.
I have a strong mailing marketing background. That could work depending on your goals but if you have the time to take the calls, you may not want to send out the blind offer b/c that will turn off a lot of possible prospects that will just throw the mailer away. If you have the time, talking to those in that situation should allow you to convert more into deals. If you're in miami, that market is hot so I don't think you need to be that low to close a deal and postage can be expensive.
If you're spending that money on marketing, I would never let it go to a vm unless you just don't have the time at all. Always want to talk to that opportunity to turn it into something. People (especially those willing to sell their property at 50% of market) can be very indecisive and may not leave a vm or change thier minds completely 5 minutes after picking up the phone. Plus inbound calls close better than outbound always. It changes the control of the call. They called you so why did they call you? Rather than you calling them trying to pitch them when calling them back and maybe catching them at the grocery etc
