Direct Mailing Campaigns

[Dylan Miracle]

I've been using YellowLetterHQ as my direct mailing system for several months now and it's pretty popular within the market that I am in (Central Valley/Fresno, CA). We usually send out about 500 mailers costing us around $0.52 per lead, we're looking to scale and send out more mailers. I am starting to think that there might be other avenues that would give us a better bang for our buck + better individuality from other investors? Does anyone know of any reputable mailing services that you've used to scale direct mailing campaigns?
