(From david@davidmelnichuk.com) I saw this form on your site, and I submitted it. Now you’re reading this, so that means it works. Awesome! But that’s not enough.

For this form to make your business money, people have to respond to you when you reach out to them. Don’t you hate it when they never answer, or by the time you get back to them, they already decided to do business with your competitor? This ends today. I made a free video tutorial that shows you how to setup an immediate SMS message and email response to go out to every lead that submits this form so you can start a conversation while they are still thinking about your services.

If you contact a lead in the first 2 minutes after they’ve submitted this web form, they’re 100x more likely to respond and 78% of customers buy from the first responder. Check out my free tutorial on how to set this up: http://bit.ly/how-to-setup-an-automatic-sms-and-email

What’s the catch? Nothing. My step-by-step training here is completely free and will show y
