Frequently asked questions
Can I create and track email campaigns?
Yes. Create campaigns, send to subscriber segments, and track open rates, click rates, bounces, and unsubscribes in real time.
How does Maildroppa authentication work?
Maildroppa uses a custom X-API-Key header (not Bearer) against api.maildroppa.com.
Can I manage subscriber lists and segments?
Yes. Create and manage subscriber lists, add/remove subscribers, and build segments with custom conditions.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
