Quickbooks sucks but Mailchimp is a good product IMO. It does have a bit of a steep learning curve but it gets the job done much cheaper than Constant Contact.
Let's hope Intuit doesn't make MailChimp as bad as Quickbooks online. Would be a shame to see a longstanding solid product become bloated and overcomplicated in the name of more profits.
Or even attempting to make it an "all things to all people" product.
It seems that those in charge of large software teams never seem to learn that there is:
1. Nothing that can be "all things to all people."
2. Simple, but brilliant for its intended purpose, beats "Swiss Army knife" complexity every time.
3. That if you can't say, in one short sentence, what a given piece of software has as its intent, then it's badly designed. (Mind you, it can be badly designed and still meet this criteria, it's just less likely).
Even things like Windows can be described briefly and in a way that encompasses what it is intended to do.
