Messages

Viewing, composing, and managing email messages

Viewing Messages

Click a message in your mailbox to open it. By default you see the rendered HTML version - the same thing a recipient's email client would display.

HTML vs Plain Text

Use the view switcher in the toolbar to toggle between HTML and plain text. If your emails are multipart, check that both versions render correctly.

Email Verification

Received messages show SPF, DKIM, and DMARC verification results. Instead of digging through raw headers, the platform checks these and tells you whether authentication passed or failed.

Raw Source

The full SMTP source of a message: headers, MIME boundaries, encoded body parts. Open it from the message toolbar.

When the verification summary isn't enough and you need the full picture, the source has everything.

Attachments

Inline attachments render directly in the message view. File attachments can be downloaded individually. You can also download the entire message as a file.

Composing Emails

Send test emails between your accounts directly from the web interface. Open any account in Mail and click Compose.

The editor supports:

  • Formatting: bold, italic, underline, strikethrough, blockquotes, lists, links, horizontal rules
  • Recipients: To, CC, BCC, and Reply-To fields
  • Attachments: files from your computer
  • HTML / Text: rich text or plain text
You can only send to email addresses that exist as accounts in your system. This is by design - nothing leaves the sandbox.

Managing Messages

Read / Unread

Messages are marked as read when you open them. You can toggle read status from the toolbar, or select multiple messages and change their status in bulk.

Flagging

Flag messages to mark them as important. Works on single messages or in bulk from the message list.

Moving

Move messages between mailboxes using the move action in the toolbar. Pick a target mailbox from the dropdown.

Bulk Actions

Select messages using the checkboxes in the message list. The toolbar updates to show bulk actions: delete, mark as read / unread, and flag / unflag.

Message Expiry

Individual messages can have their own expiry timer, independent of the mailbox-level auto-delete. Once the time runs out, the message gets deleted.

Printing

Print a message from the toolbar. Opens your browser's print dialog with the message content.
