Frequently asked questions
Can I send transactional emails with templates?
Yes. Send emails using pre-built templates with dynamic variables, or send raw HTML content with full delivery tracking.
Can I manage domains and DNS records?
Yes. Configure sending domains, verify DNS records (SPF, DKIM, DMARC), and monitor domain health and reputation.
What API does MailerSend use?
Bearer authentication against api.mailersend.com/v1.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call MailerSend tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
