Follow these five steps to make sure your email looks great.
Outlook is the most bullish of all email clients and seemingly can’t adjust image sizes. Make sure the email looks great before moving on.
Include any responsive styles you want to include. These should be in a the
<head> of your document within a <style> tag.
Once your email looks great in Outlook and responsive styles are included, bring your styles inline, which you can do with a variety of services.
We recommend Foundation for Emails (Inky's) Inliner to do this.
Don’t send it out just yet! Make sure you test it on as many platforms as you can. We use Litmus to test on a number of devices. You should too.
