Shared team email testing using this MCP Server

Commit your `.vscode/mcp.json` config to the repository to let your whole team use this MCP Server. Developers can run `send_email` directly from Copilot Chat to verify template rendering. The team can also fetch shared layouts with `get_templates` to ensure local code matches the latest production designs without logging into the Mailgun web UI.

Debug production delivery issues in Copilot Chat

When troubleshooting customer tickets, ask Copilot to run `list_logs` to find specific delivery events. You can filter by recipient address to see exactly when an email was dropped or bounced. If a customer is on the suppression list, use `list_bounces` to locate the block. You can then call `delete_bounce` to clear it, resolving the customer's issue without leaving your editor.

Monitor sending domains and DNS settings

Keep tabs on your production domains using `list_domains` in your chat window. Copilot can check domain verification status and flag issues before they impact deliverability. Run `get_domain` to inspect DKIM and SPF records directly. You can also fetch sending metrics using `get_stats` to verify that your bounce rates are within safe limits.
