One way to do a quick check on the effectiveness of your email templates is to get some quick feedback. One way to do this is to set up your template and create a mini campaign.
If what you're looking for though is just a simple way to get some feedback, the Seven Second Test is a really good way to do that. Not only does it give you a link sharing option but it gathers quick feedback much like a survey. Here's how to set it up.
Go to your Templates screen then click the Seven Second Test button highlighted below
Click the dropdown to select a template
Click on the template you want to test then click on Select
Click the Copy button and send the link to whomever you want to take a look at the campaign
What your respondents will see
