Drive by direct mail letter salutations?

[Chris Stromdahl]

I have been systematically driving for dollars and have collected a significant list.

Two things:

I can go online to the county assessors office to collect the owner's name, mailing address, etc. Do you think that this is a productive use of my time?

OR

I use a generic salutation, run the leads through a series of mailer campaigns and discard the leads that do not produce results. If you think this is a better use of my time, what salutation do you suggest that I use keeping in mind that I have no idea who the owners are?

Thanks, Chris
