One of our clients asked for mobile friendly email and we used their PSD and sliced it and used it mailchimp. The result was good and we tested on many devices and it looked great. However cleint was upset that we sliced the image and did not create an HTML version (code your own)to make it mobile friendly and ended the contract. We were only asked to do mobile friendly and they had a very limited budget. What do you guys think? Should we have done it differently? Are html or custom code better in mailchimp?

Thanks!
