Manage subscriber lists with Claude Desktop

The Mail Blaze MCP server lets you pull and modify your audience data right in the chat interface. You can run `list_subscriber_lists` to see every active segment without leaving your workspace. Your agent grabs the exact list ID, then uses `list_list_subscribers` to dump the current roster so you know exactly who you are talking to. Adding new leads happens instantly. Tell your client to push a new email address, and it fires `add_subscriber_to_list` with the required UID and subscriber data. If someone opts out, `delete_list_subscriber` strips them from the database immediately. You never have to log into a separate marketing dashboard to keep your lists clean.

Draft and stage emails

Building a new broadcast starts with `create_new_campaign` by passing a JSON body with your subject line and content. This tool stages the email inside your account. You can ask Claude to review past performance first by pulling `list_email_campaigns` to see what worked last week. Need specifics on a draft? The `get_campaign_details` tool returns the exact configuration for any specific campaign. Your AI client checks the sender name, reply-to address, and list assignment before anything goes live. That prevents embarrassing mistakes where you send a promo code to the wrong segment.

Send campaigns and update profiles

Triggering a live broadcast requires the `send_email_campaign` tool. Once you confirm the draft looks good, your agent hits the endpoint and the emails go out. You control the timing, and the MCP server handles the execution. Keeping individual records accurate is just as easy. If a user changes their name or preferences, `update_list_subscriber` modifies their existing profile in place. This keeps your delivery rates high and ensures your next batch hits the right inboxes.
