Shareable Previews
Shareable previews are built for quick QA with teammates and clients, not permanent storage.
How Share Links Work
When you create a shareable link, MailMode stores a sanitized rendered version of the current preview and returns a long random public token. The public page shows the email preview without exposing a database ID.
Expiry
Shareable preview links expire after 3 days. Hosted previews include an expiry notice and are deleted by server-side cleanup once expired.
Public Access
Anyone with the link can view the preview while it is active. Do not use shareable previews for sensitive, confidential or personal information.
Temporary Processing
Normal pasted/uploaded previews are processed temporarily. Hosted share links store only what is needed to display the preview until expiry. ZIP image assets may be embedded into the stored rendered HTML as data URLs.
Privacy Notes
MailMode uses Cloudflare Web Analytics and Vercel Web Analytics for basic usage, performance and traffic trends without analytics cookies or localStorage tracking. Newsletter subscriptions are managed through beehiiv, and subscribers can unsubscribe from any MailMode newsletter email.
Security Notes
Hosted previews are rendered in sandboxed frames where possible, scripts are stripped or disabled, and tokens are long and unguessable. Still, a share link is public if someone has it.
