When I started my personal business, Mail Chimps is the marketing service provider that I used to build customer pool and sending them update on email for my brand. My husband helped with the initial set up but once things were in place, Mail Chimps made everything easy enough that I was able to engage new customers and retain previous ones as well.
The subscription system they made for my product is very intuitive, and I really like seeing how many people get to subscribe themselves!
Mail chimps is a great platform to setup your business marketing and it help to make your customers to get to you right in time!! I love it!
