Export your data

You can export everything in your SuperMail workspace at any time. No lock-in.

How export works

Mailbox export is an asynchronous, email-notified flow:

• Format: standard .mbox, one file for your workspace.
• Delivery: we email you when the export is ready, with a download link that works for 7 days.

The billing settings page also lists recent exports, their status, message count, file size, and a download button while the link is still valid.

What’s included

• All synced messages in all folders, including Spam and Trash.
• The message body as stored in SuperMail, written into a standards-readable MIME message.
• Attachments inline in the mbox file (no separate download).

What’s not included

• Drafts that haven’t been saved.
• Account settings, contacts, tags, send profiles - those aren’t email and aren’t exported.
• Billing history (see Settings → Billing → Invoices for PDF invoices).

Importing elsewhere

Exports use a standard .mbox format that works with common apps like Thunderbird and Apple Mail. If you use another mail tool, search its docs for “import mbox.”

Thunderbird: use the ImportExportTools NG add-on → Import mbox file.

Apple Mail: File → Import Mailboxes → Files in mbox format.

Export on cancel

After cancellation, exports remain available for the full 30-day read-only window. Once your account is fully closed, exports are no longer possible.
