What is Inbox Preview?

Inbox preview is a paid feature in partnership with Litmus, the leading email and spam testing tool.

It is critical for successful e-mail marketers to know the way their content is displayed in order to score higher rates of engagement. The challenge today is that an email to 20 individuals could be displayed in 20 different formats! VBOUT’s Inbox Preview allows you to preview the email across multiple systems in seconds.

With Inbox Preview, you are able to test how your email templates will look like before you send them out to your subscribers. Here is a list of the email clients available for testing:

How can I run my tests?

We conveniently placed the option to run your tests in the following 3 sections:

  1. Directly from the manage campaign page, ACTIONS drop down. Below is an example with A/B testing activated and you can test both versions of the campaign.
  2. From the email builder top right hand TOOLS drop down:
  3. If you are using the simple html editor, you can access it directly from under the editor area:

Once you click on the Inbox Preview you will be prompted with the popup below to choose which email client to test:

After choosing from the options available, the engine will generate the previews in a popup window and provide the following controls:

  1. Ability to re-test your chosen email clients.
  2. Create a new test and add new email clients.
  3. Two results will be shows, one is the preview of the campaign with images blocked, another preview with images unblocked.
  4. You can preview the history of your tests in case you made edits to your content and ran multiple tests.
  5. Number of available credits.

How can you get access to this powerful add-on?

Inbox Preview is only available for paid plans and is based on Credit Usage. Each email client you choose will use one credit and each time you RE-TEST you will use an additional credit. Your credit allowance will reset at the end of each billing cycle no matter how many credits have been used.

If you are doing A/B testing, you will have the option to choose the test for each version of your campaign:

Here is a quick example: if you chose Android 6, iPhone 6s and Gmail (Chrome) you will use 3 credits. If you make edits and run the test again on the same email clients, 3 additional credits will be used.

If you are using a free version of Vbout you can easily purchase an add-on from our add-on center.
