@Wayne KingI have not used them, although I've heard of them a few years ago.However, if you are still on the fence after finding someone who used them - Buy a few leads—start with a small test amount—and assess their quality for yourself.

This has been court tested by over 40 years of case law. 

If the goal is still the goal and you are willing to do anything to achieve it, then test everything, don't set a path in stone that you cannot come from out of. 

Just wade in, figure it out, test it out.

If you use any of the major mailhouse services, like Yellow Letter HQ (a service I can personally vouch for), they offer a variety of templates and even provide text suggestions.A smart way to analyze this strategy is by observing people in your local market who use mailers and identifying what works or doesn’t work for them.The simplest and most effective way to test this approach is to pull a hyper-targeted list of distressed homeowners and run a small-budget mailer campaign.Hope this helps!
