HTML ignored, adding linebreaks

Hi there,

I have used other two services that are not Mailgun. My last one was Sparkpost, all my HTML was being respected by the plugin and all <br> linebreaks were working fine.

With Mailgun, though now my emails are painting the <br> tag as well… which means Mailgun is ignoring any HTML.

How to make sure Mailgun uses the HTML included on the message?

Thanks for your help.
