Is there a feature/tool in Marketo to see what my HTML email will look like in multiple email clients? Campaign Monitor has this feature. For a fee of $5 per test, you can see how your email looks in virtually EVERY email client, in every possible use case.
How do I run a similar test, in Marketo, before I send out a campaign? And I don't mean "send a test email." I mean visual feedback of how my email will look in many different clients.
Marketo doesn't have this feature, but we use Litmus to do this. It's $49 for a single license, and you can get both screenshot and live previews of your emails in every client you can imagine. http://litmusapp.com/
