RAG for Mailify (Sarbacane) Campaigns

You need marketing answers based on actual performance, not guesses. By connecting the `list_email_campaigns` and `get_campaign_details` tools, LlamaIndex pulls your historical broadcast data directly into a queryable vector store. When someone asks about last quarter's engagement, the agent avoids hallucinating. It runs `get_campaign_performance`, retrieves the hard click rates, and synthesizes an answer grounded entirely in your live API data.

Index Address Books with this MCP Server

Context matters when segmenting users. The `list_address_books` and `get_address_book_details` tools allow your LlamaIndex application to map out exactly how your audience is divided before generating new content. Your agent reads the metadata for every list. If a user asks which segment receives the newsletter, the system queries the index, finds the right list ID, and returns the exact subscriber count.

Ground Answers in Live Contact Data

Sometimes you need to know exactly who is on a specific list. LlamaIndex uses `list_book_contacts` to fetch the raw subscriber data and embed it into your knowledge base. You can then ask your agent if a specific VIP client received a recent promotion. It checks the indexed contacts, verifies their presence, and confirms their status without you ever logging into the marketing dashboard.
