Seen two split tests where they both got a 400% increase in closed clients.
Those that correspond via email have a lot lower closing ratio
than those that talk over the phone.
Think about it, for no added marketing cost,
you may get your client 4 times more clients/customers.
No more SEO, radio, tv, yellow pages, newspaper, direct mail campaigns.
It's like free money.
Just from optimizing what they are already doing.
