We use MailJet.

It's very easy to use. 

The best feature that I love, is that you can filter and export Only Opened mail lists from your campaigns.

And also their prices are good.

You can read reviews of MailJet here.

Aweber and Convert Kit are great for the price, I know of a few people who use those as the main alternatives to MailChimp. I also remember someone mentioning that Campaign Monitor is one to avoid because it's expensive and isn't any better than the alternatives.

I'd suggest checking out Email Octopus, https://emailoctopus.com/ 
I don't personally use them, but their pricing and product are impressive. There are of course many other alternatives, but when using MailChimp as a direct comparison, I think this has a lot going for it.

Campaign Monitor is my email marketing platform - costs me about $12 per month, no coding in required and the templates look lovely on desktop and mobile. You can also build sequences and do a bunch of other things. It's a great choice for SMEs.

I've used a number of email marketing platforms and while Mailchimp is very easy user-friendly with great templates and reporting features, there are some great alternatives on the market. In my experience, I think the best MailChimp alternatives are Moosend and Hubspot.

Moosend has a great Free Forever plan that gives you unlimited emails, customer segmentation and reporting and analytics features. If you upgrade to the Pro plan for $8 p/month you can also get access to landing pages, popup forms, sign-up forms and more. Moosend is probably the best alternative to Mailchimp in terms of value for money. 

Hubspot is another awesome Mailchimp alternative and offers a suite of tools for email marketing, marketing automation and CRM integration. It's easy to use and the advanced features make it an ideal platform for businesses that are growth-focused.
