Terms of Service

1. Use of the Service

MailMode is an email preview and testing platform designed to help developers, marketers and teams preview email rendering across light and dark modes.

You agree to use MailMode responsibly and lawfully.

You may not:

• upload malicious code or harmful content
• attempt to disrupt the service
• abuse shareable links or infrastructure
• use MailMode for unlawful activity

2. Uploaded Files and Local Processing

MailMode can process pasted HTML, MJML, React Email files and zipped email projects for preview and analysis.

When you paste code or upload a file for local preview, the content is processed in your browser where possible. ZIP projects are checked and unpacked in browser memory, and supported image assets may be converted to data URLs so they can appear in the preview.

Uploaded or pasted content is not stored on MailMode servers unless you choose to create a shareable preview link.

You are responsible for making sure you have the right to upload, preview, analyse and share any email content or assets you use with MailMode.

3. URL Loading

If you load email source from a URL, MailMode may fetch that URL through the server so the browser can preview it. URL responses are used for the preview workflow and are not permanently stored by URL loading itself.

You should only load URLs you are authorised to access and test.

4. Shareable Links

MailMode may generate public shareable preview links when you choose to create one.

Shareable preview links store a sanitized rendered version of your email, along with metadata such as the preview token, creation time, expiry time, selected preview settings, view count and last viewed time.

Shareable links expire after 3 days. Expired previews are intended to be automatically deleted, but deletion timing may depend on server cleanup jobs and infrastructure availability.

Anyone with the link may be able to access the preview until it expires or is removed. Please avoid creating share links for sensitive, confidential or personal information.

If a shareable link is created from a ZIP project, local image assets may be embedded into the stored rendered HTML as data URLs so the preview can display correctly.

5. Availability

We aim to keep MailMode available and reliable, but we do not guarantee uninterrupted access.

Features may change, be updated or removed at any time.

6. Intellectual Property

MailMode, including its branding, design and software, remains the property of MailMode.

You retain ownership of your uploaded email content.

7. Limitation of Liability

MailMode is provided “as is” without warranties of any kind.

We are not liable for:

• rendering inaccuracies
• email client inconsistencies
• lost uploads
• temporary downtime
• indirect or consequential damages

8. Privacy

Your use of MailMode is also governed by our Privacy Policy, which explains temporary file processing, Cloudflare Web Analytics, Vercel Web Analytics and beehiiv newsletter subscriptions.

If you subscribe to the MailMode newsletter, you may receive MailMode updates, release notes, email development tips and announcements about future apps or app releases from the same creator or team. You can unsubscribe using the link included in newsletter emails.

9. Changes

We may update these Terms from time to time.
