Install and connect
- Install the Conterminal Chrome extension for desktop bulk sending, or install the Google Workspace add-on for Gmail mobile and open-message sending.
- On desktop, select one or more Gmail conversations and select the Conterminal button beside Gmail's utility controls. Review and send from the compact dropdown. The pinned Chrome toolbar icon opens the side panel as a fallback.
- On mobile, open a message and select Conterminal from the Gmail side panel.
- Grant the requested read-only Gmail permissions.
- Sign in to Conterminal if your mailbox is not already linked.
Send attachments
- Review the attachments detected from the selected messages.
- Confirm Delivery Order, Proof of Delivery, or Other Document.
- Exclude any attachment that should not be submitted.
- Select Send selected to Conterminal.
- Follow the Document Review link to monitor processing.
Supported files
Delivery Orders accept PDF, DOC, and DOCX files. Proof of Delivery and Other Document submissions accept PDF, JPEG, PNG, and TIFF files. Cloud-drive links without attached files are not submitted.
Troubleshooting
- Refresh Gmail after a new installation.
- If desktop bulk selection is not detected, reselect the Gmail rows and reopen Conterminal. Use the pinned Chrome toolbar icon if the in-Gmail launcher is not visible.
- Confirm you are signed into the mailbox where the add-on was installed.
- Ask your Workspace administrator to allow Conterminal if installation is blocked.
- Retrying the same attachment is safe; duplicate submissions return the original result.
