One of the hardest parts of testing your email is testing the compatibility of your template with different email clients. Sendwithus alleviates this pain with Device Testing which allows you to view what your email will look like, before it reaches the inbox.

What is Device Testing?

Device Testing allows you to test your emails before you send them out. You can select from 40+ different email clients ranging from different browsers, operating systems, and mobile devices.

Using Device Tests

In your Sendwithus dashboard click Templates.

Pick a template to test and click the Edit button. In the Template Editor, click the Device Tests tab to bring up this section.

From here, you will see two options: Select Devices or Run Device Test.

Select Devices

In this menu you can select all devices you would like to view a preview from.

There are 12 devices preselected by default. These selected devices are the 12 most popular selected devices.

Select Devices

Once you have selected the desired devices, click the Save button.

Run Device Test

This button will generate the Device results from the devices you have selected.

You will need to click this button every time you make a change to the selected devices or make a change in the template. You will be prompted with red text beside this button to notify you that your Device Test results are outdated.

View Customer’s Device

With Device Testing, you can see which device a customer has viewed the email on.

In the Sendwithus dashboard, go to the Customer’s page and search for a customer. On the Customer Details page, click the Details button on an email you would like to view.

Here you can see the email was opened on an iPhone. “SendGrid: Recipient has opened the HTML message using an iPhone (iOS)”

Click on Details

We can go one step further and see exactly how the customer viewed that email! Click on the View Email drop down button and select View on Device.

Troubleshooting

Error Displaying Preview

If you get a gray screen with a triangle error in your Device tests, it means the current device could not generate the results.

Error Displaying Preview Error Displaying Preview Group

This happens because the service for the current device is down. You can check the Litmus Status Page for device testing updates.

If there are no errors on the Litmus status page, try regenerating the Device Test.

Red Text Outdated Template

If you have modified your template, red text will appear beside the Run Device Test as “Template has changed, re-run tests to get updated results.”

Template Changed
