Inbox Vision

Inbox Vision allows marketers to view their emails from the perspective of various email clients and mobile devices. Access Inbox Vision from the email editor by clicking Preview and Test. It also allows you to spam test from the Spam Test tab.

Test Your Email

To test your email message in Inbox Vision, click Preview and Test within the email composer. Braze then sends an HTML version of your email to various email clients used across the globe, which may take between two and ten minutes to complete.

Braze will then display screenshots of a sample, rendered HTML on desktops, mobile devices, and tablets. The devices in which screenshots are displayed are scrollable, to allow for better viewing. If you encounter unclear screenshots for certain email clients, click Reprocess Screenshot to create another screenshot.

If you run an Inbox Vision test, you will also receive a code analysis and spam testing results.


Once you make changes to a template, you will need to click Re-Run Test to see the effect of the changes on the previews.

Code Analysis

Code analysis is a way for Braze to highlight issues that may exist with your HTML, showing the number of occurrences of each issue and providing insight into which HTML elements are not supported. This information can be found on the Inbox Vision preview page by selecting the list icon in the upper left-hand corner.
