Mailbird Next includes several attachment tools for adding files to outgoing messages, previewing received attachments, saving files, and managing downloaded attachment data.

📎 Attachment features

• Add attachments by selecting files or dragging files into a compose window.
• Attachment Quick Preview lets you preview supported attachments without fully opening them in another app.
• Pin attachments to the top of a message so important files are easier to find in long conversations.
• Drag attachments to Finder to save received files quickly on macOS.
• Save all attachments helps save multiple attachments while avoiding accidental overwrites in the same folder.

• Delete cached attachments can free up local storage. Simply right-click on the attachment and choose "Delete from cache".

  

🧭 Common workflows

1. Open the message or compose window that contains the attachment workflow you need.
2. Use the attachment icon, attachment menu, preview option, or drag-and-drop action shown in your version of Mailbird Next.
3. If saving files, choose the destination folder and confirm the files saved correctly.
4. If freeing up space, remove cached attachment data when you no longer need the local copy. This will only work for emails you have received.

⚠️ Limitations

• Preview support depends on the attachment file type and the viewer available on your device.
• Deleting cached attachments removes the local downloaded copy, not necessarily the original file on the mail server.
• Large attachments can fail to send if they exceed your email provider’s size limits.
• Some attachment downloads may be blocked by antivirus, firewall, provider restrictions, or local storage permissions.
