Inbox Preview
01 Definition
Inbox Preview meaning: A rendering of how an email will look across different inboxes before sending.
Inbox preview shows how an email will display in various mail clients and devices without sending it to real recipients. Testing tools generate screenshots for each environment so senders can catch layout, image, and font issues. Previews are snapshots of supported clients and may not capture every personal setting or client update.

Why it matters
How Inbox Preview fits the work
Checking appearance across inboxes before sending helps prevent broken or unreadable emails from reaching your audience, protecting the brand impression.
In context
The inbox preview reveals that a background color drops out in Gmail, so the team adjusts the design before scheduling the send.
Practical note
A preview is a static render, so it cannot reproduce every recipient's font size, dark mode choice, or image blocking; treat it as a strong guide, not a guarantee.
