Inbox Preview: See How Your Emails Look in Real Inboxes (Labs)

Overview

You can now preview how your emails will actually appear across different email clients with the new

Inbox Preview

feature in the email builder.

Instead of relying on standard desktop or mobile previews, you can see how your emails render in real inboxes, including Gmail, Outlook, Apple Mail and more, so you can catch rendering issues before your emails reach customers.

🌟 What's New

📧 Real Email Client Previews

Preview how your email appears in email clients like Gmail, Outlook and Apple Mail.
See actual email rendering, captured from the real client, instead of relying only on simulated desktop, tablet or mobile previews.
Preview as a specific contact to see your email with their personalized details filled in.

🖥️ Preview Across Multiple Email Clients

Select the email clients you want to test, or start with the popular ones we've picked for you.
Filter by device (web, desktop, mobile) and mode (light, dark), and pin the clients you check most so they're selected every time.
Compare layouts across clients to spot inconsistencies in formatting, images and design.
Open any preview full size and move between clients for a detailed inspection.

🔍 Identify Rendering Issues Before Sending

Catch Outlook rendering issues, dark-mode inconsistencies and Gmail content clipping before your emails reach recipients.
See your email's estimated size, with a warning if Gmail will clip it.
When you edit the email, Inbox Preview shows which previews need updating, so you're never reviewing an old version.
