Manage audiences with the VS Code MCP Server

The Mail Blaze tools let your development team interact with marketing lists directly from their editor. Running `list_subscriber_lists` exposes all available segments so you know exactly which UIDs to target in your code. Copilot can then execute `list_list_subscribers` to pull down the actual roster for debugging sync issues. Adding users to a list requires the `add_subscriber_to_list` tool. You pass the list UID and subscriber data, and the record appears in your account. Need to test an unsubscribe webhook? The `delete_list_subscriber` tool drops the user instantly so you can verify your application logic handles opt-outs correctly.

Stage emails from your editor

Building a broadcast programmatically is simple when `create_new_campaign` handles the heavy lifting. You provide a JSON body with the details, and the tool creates the draft. If you want to see how previous emails were structured, `list_email_campaigns` returns your account's full history. Verifying that draft is critical before sending. Copilot uses `get_campaign_details` to fetch the specific configuration of the email you just staged. This ensures your subject lines, lists, and sender profiles are perfectly aligned before anyone hits send.

Send campaigns and update profiles

Dispatching a finished email relies on the `send_email_campaign` tool. Your agent triggers this endpoint to push the broadcast to your audience. This MCP capability lets you test end-to-end email flows without ever leaving your IDE. Keeping your data fresh is handled by `update_list_subscriber`. When a user changes their email address in your app, Copilot can test the API call to modify their existing record. The change happens immediately, keeping your marketing database perfectly synced with your backend.
