Options

Section syntax
Use the shown heading, bullet and link forms. The supported structure creates a deliberate table layout without inventing newsletter content.
Preview and footer
The preview line is hidden in the message body; clients may display it differently. The footer and unsubscribe link remain your supplied text and destination.

Supported inputs and limits

Up to 12,000 section characters, 40 blocks and 60 links. No images, tracking pixels, scripts or remote preview requests. Limited email-layout subset; provider compatibility and unsubscribe compliance require separate review.

Where your input is processed

This tool processes your input in this browser. Your text and files are not uploaded to UseFreeTools. Check this tool's limits for anything it may save on your device.

Email clients can ignore parts of a layout

Inline styles and the small responsive block cannot guarantee identical rendering in every provider. Test the exported message before sending and confirm the destination links. This builder neither sends mail nor checks consent, mailing-list state or unsubscribe processing.
