(From eric@talkwithcustomer.com) Hello knutsonchiropractic.com,

People ask, “why does TalkWithCustomer work so well?”

It’s simple.

TalkWithCustomer enables you to connect with a prospective customer at EXACTLY the Perfect Time.

- NOT one week, two weeks, three weeks after they’ve checked out your website knutsonchiropractic.com.
- NOT with a form letter style email that looks like it was written by a bot.
- NOT with a robocall that could come at any time out of the blue.

TalkWithCustomer connects you to that person within seconds of THEM asking to hear from YOU.

They kick off the conversation.

They take that first step.

They ask to hear from you regarding what you have to offer and how it can make their life better. 

And it happens almost immediately. In real time. While they’re still looking over your website knutsonchiropractic.com, trying to make up their mind whether you are right for them.

When you connect with them at that very moment it’s the ultimate in Perfect Timing –

(From eric@talkwithcustomer.com) Hey,

You have a website mikulachiropractic.net, right?

Of course you do. I am looking at your website now.

It gets traffic every day – that you’re probably spending $2 / $4 / $10 or more a click to get.  Not including all of the work you put into creating social media, videos, blog posts, emails, and so on.

So you’re investing seriously in getting people to that site.

But how’s it working?  Great? Okay?  Not so much?

If that answer could be better, then it’s likely you’re putting a lot of time, effort, and money into an approach that’s not paying off like it should.

Now… imagine doubling your lead conversion in just minutes… In fact, I’ll go even better.
 
You could actually get up to 100X more conversions!

I’m not making this up.  As Chris Smith, best-selling author of The Conversion Code says: Speed is essential - there is a 100x decrease in Leads when a Lead is contacted within 14 minutes vs being contacted within 5 minutes.

He’s backed up by a
