Inbox Rendering

Introduction

Inbox rendering is a standard feature in Mapp Engage that allows you to verify the optimality of your message's design and content before sending a campaign. Your system includes the first 100 inbox rendering tests, but a fee is charged for each additional test. Contact your account manager for more information.

Inbox rendering is an actual sendout to test addresses, not an artificial simulation.

When you start the process, Mapp Engage sends the email message to various seed addresses on different platforms, clients, and ISPs. Mapp Engage then captures a screenshot of the message displayed in each email client's environment. These screenshots are displayed as thumbnails. Previews can be sorted and filtered by criteria or selected and exported to a common screen for printing or saving.

Perform an inbox rendering check before every sendout to make sure your email message and sendout settings are in top form. The check takes only minutes to perform and gives you the concrete feedback you need to optimize rendering, deliverability, and user experience.

Use Cases

Inbox rendering lets you:

• Preview your message in over 30 email clients and devices.

• Check for spam triggers and verify sender identity (DMARC, DKIM, SPF).

• Test subject line length, list-unsubscribe header, and links.

• Compare displays with "images on" vs. "images off".

• Spot layout, formatting, or image issues early.

Images​

You can view the message either with or without images displayed. Many email recipients and some email clients have a default setting that initially suppresses the display of images in an email. The recipient can manually display the images with a link or button. If images are suppressed or blocked, the recipient sees only the text of the email and symbols for the suppressed images.

Please note that creating an ALT text is only part of the solution. Not all email clients display the ALT text. Some email clients do not consider the ALT text and only display the empty frame where the image should be, even if an ALT text has been entered.

Message rendering without images provides you with an impression of what information is presented in your message without graphics. Deactivating images significantly impacts the effectiveness of your email in the inbox. When you only rely on images to communicate your content, your recipients may see an empty email when they open your message. Therefore, the message preview without images is important to consider.
