What do you like best?
As I am new into email marketing, I was looking for affordable and good solution, but what I found is great. Elastic mail is great in terms of setup, features, templates (both drag & drop feature can be used with raw html editor), reporting tools, A/B testing, Dynamic IP at a very reasonable rate, free 5000/daily emails (which is great for start ups), and after free mail it's just 0.09$ per thousand mail, it's just so much affordable with lots of great features.
In elasic mail you will get a lot of API to integrate with your systems and open sources. You can allot sub accounts to your colleagues, customers, friends to manage it. If you'll not send good emails, your reputation will lose and it's a perfect thing that other spammy users couldn't impact your marketing.
In one line, it's the best tool for email marketing. Go for it.
What do you dislike?
Domain / SPF / DKIM setup is little bit pain, it should have a clear and easy documentation. WordPress integration is little tuff, email bouncing detailed report need some improvement.
I tried to upload duplicate contacts with more information, I couldn't do it. It needs to improve, other than these I find everything is perfect.

I use Elastic mail for my email marketing, newsletter campaigns. It works great, you can use HTML form given, can set premade templates, can set differnt-2 templates for each campaign. I use it and I get great results.
We use it for affiliate marketing as well, we used it free version of 5000/daily emails and started earning it without spending a single penny.
We also use it for our clients, who don't have much budget for email marketing, it's perfect solution for them. Sub-account section is great.
