Email Testing

Email Testing allows you to see what your email will look like when your customer opens your email on their device.
​
Your Knak contract will include an email testing package that will include a certain number of tests. A single 'test' refers to each time you select the email testing button from the email preview screen:

If you want to know know how many tests you have used and/or how many you have left on your current contract, please reach out to your customer success manager.

With Knak's Email Testing feature you can see how your email looks on different devices, operating systems, browsers, email platforms and light and dark mode.

To test how your email will look on different devices, open the email you want to test, choose the drop down menu to the right of the email name and choose Preview.

Then you will choose the icon with multiple devices, 3rd from the left on the navigation bar.

From there, you can see all of the testing options that will be available to you with Email Testing including Gmail, Outlook, Chrome, Firefox, IOS/Android, Mac/PC, Light/Dark Mode.

Click the 'Generate Previews' button.

You'll see thumbnails of all the testing. Click the one you'd like to view.

From this page, you can also 'Refresh Previews' and filter the view by Device and Light/Dark Mode.

Once you click into the thumbnail of a test, you'll see how it will look on that device.

✨ Ta-Da! ✨

Make note of any changes you may need to make in your email so that it looks as expected across devices.

To choose another email test, choose another thumbnail from the right side menu. Alternately, toggle back to a full screen view of the thumbnails by clicking the blue "<" arrow 3/4 of the way across the top of the screen, just under the navigation bar.

When you're done reviewing your email tests and ready to go back to the builder, click 'Exit Preview' in the upper right hand side of the navigation bar.

As an admin, you can control who can generate previews. This can be important if you are trying to limit the amount of tests. To allow users other than admins to have the ability to generate email previews, please turn on the 'Can generate email client previews' permission within the role you'd like to allow this for.

When you create an email, you may include images to make it more visually appealing. However, these images can sometimes be quite large and take longer to load. The vendor we use for email test previews grabs the screenshots of the email previews quickly, so if the email has image files that are quite large and do not load immediately, this can display an incorrect test preview even though the live email would display correctly.

For emails we usually recommend trying to keep images under 1MB. A good rule of thumb is to export images at 2x the width they’ll appear in the email. So if the image is going to be 600px wide in the email, it should be exported at at 1200px to keep things looking crisp for retina. GIFs are the one exception here since Outlook tends to stretch them if they’re too big.
