Semantic indexing for LlamaIndex

Transform your email logs into a searchable knowledge base. By passing the output of `list_campaigns` or `get_subscriber_activity` into your index, you make past performance data queryable by the agent. This stops your agent from guessing about campaign history. It draws facts from the actual API records stored in your vector index.

Grounded marketing insights

Stop hallucinations by grounding your agent in real-time data. When you call `get_automation`, the result is indexed immediately, allowing for precise queries about automation structure. Your agent answers questions based on current data, not stale training sets. It links your marketing operations directly to your RAG pipeline.

Unified data access via MCP

Access subscriber groups and segments as part of your document store. The `list_group_subscribers` tool pulls the data that LlamaIndex then categorizes for your application. This creates a single source of truth for your agent. It sees the list of subscribers as just another piece of context to be searched and retrieved.
