Doesn’t format properly

I’m attempting to use this plugin, but the HTML emails show up in google with a super-wide format and broken tags. Thinking that maybe the pro version’s “Premium Styles” functionality would solve this issue, I foolishly bought a 5-site license. In order to finish the upgrade, you’re required to install “a3 Dashboard” and link it to your account on the a3 website. Unfortunately, linking doesn’t work – their dashboard won’t recognize my account – so I’m stuck with a non-functional plugin, and an upgrade I’ve paid for but can’t use. I put a ticket into their support system 4 days ago and have yet to hear back from them. Garbage plugin. Use something else. I wish I could go lower than 1 star.
