Mailchimp is a multi billion dollar company with 15 million + customers now. How many support people do you think it takes to respond to hundreds of thousands of customers? I think you're asking for India style call center customer service instead of their local customer service. I imagine the amount of people who use Mailchimp and need support is much larger than you think. The name of company and brand probably attracts the majority of their customers. What sort of technically adept customers do you think make decisions based on something looking fun?
