I'm looking for any feedback on some of the top email platforms out there on the market today. As a front-end developer, I'm tasked with building out responsive email templates upon completion of design. The email then will be sent out with different copy, images and links based on the individual user lists we've created edited by our non-technical content editors. The issue that we struggle with in our current workflow is that editing the links, copy and images has not been easy and often requires me to go back in and edit the HTML manually or having a front-end developer, like myself, enter content each time.

Are there any email platforms out there where people find it easy for non-technical users to easily update templates, change links and add any tracking codes? Any information would be helpful. Thanks.
