HTML Responsive Email

Hello,

I'm a newbie to this topic, so please bare with me. I been working on this for days now, but just cant get it right.

I used to use Mac Mail Stationary until it got discontinued. I then came across Mail Designer 365 with lets you design Email templates and modify them too.

I designed a html email now which I am happy with, but I cant figure out how to export / integrate it to my mac mail. I have it as a html file on my macbook and went through the steps "open with safari" (in safari it opened the template perfect. Then from safari i went to "sent via email". It opened my Mac Mail and included the template, but template shows up all wrong. Part of the Banner is longer then the rest, the footer is also way too long and therefor shows up only half way....

I tried using mailchimp, but since I dont do email campaigns (just want to send to single recipients) its seems way to complicated. Also it is important to me to actually see the emails I sent in my Mac Mail outbox.

I have an account with bluehost, could I upload the file there? Would that help?

I really hitting the wall here, and am desperate for some help! Thanks in advance!!
