Email Subject & Preheader Preview
Preview how your sender name, email subject, and preheader work together across desktop and mobile inbox layouts before you send.
Inbox Preview
Switch layouts to review hierarchy and likely truncation at different widths.
Inbox rendering varies by client, device, font, width, account settings, and message metadata. Use this preview to compare wording, not as a pixel-perfect guarantee.
How to Review the Inbox Message
Read the subject and preheader as one short sequence, then check what remains visible in the narrower layout.
Put the most important product, offer, update, or action near the beginning of the subject.
Use the preheader to explain the benefit, audience, deadline, or next step without copying the subject.
Check whether the first visible words still communicate a complete and accurate idea on mobile.
Preview and Data Guidance
The preview helps you review copy structure, but delivery and rendering still depend on your email platform and recipient environment.

Frequently Asked Questions
Understand what the preview represents, why layouts differ, and how the entered content is handled.
What does an email preheader do?
A preheader is the supporting text many inboxes show beside or below the subject line. It can add context, complete the idea, or clarify what the reader will find after opening.
Is this an exact Gmail or Outlook preview?
No. This is a generic inbox preview for checking hierarchy, clarity, repetition, and likely truncation. Actual display varies by email client, device, font, inbox width, and user settings.
Why does the visible text change between desktop and mobile?
Mobile inboxes usually have less horizontal space. The preview changes width so you can see which words are likely to remain visible when the available space becomes tighter.
Does this tool send or save my email content?
No. The sender details, subject, and preheader are used only to build the preview in your browser. This tool does not send an email or store the entered content.
Should the subject and preheader repeat the same message?
Usually they work better as a pair. Use the subject for the main reason to open and the preheader for useful supporting detail instead of repeating the same sentence.
