How much would you charge a client to add a newsletter system into their website?

Hi,

How much would you charge a client to add a newsletter system into their website?

I’m going to be using MailChimp to embed the newsletter into their system. I will use the free version as the client isn’t a massive client of him in relation to it’s size of their business. It’s a car wash business.

Thanks,
Liam.

Here are few good articles I found.
