Postmark Automation via Rube MCP
Automate Postmark transactional email operations through Composio's Postmark toolkit via Rube MCP.
Prerequisites
- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
- Active Postmark connection via
RUBE_MANAGE_CONNECTIONS with toolkit postmark
- Always call
RUBE_SEARCH_TOOLS first to get current tool schemas
Setup
Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.
- Verify Rube MCP is available by confirming
RUBE_SEARCH_TOOLS responds
- Call
RUBE_MANAGE_CONNECTIONS with toolkit postmark
- If connection is not ACTIVE, follow the returned auth link to complete Postmark authentication
- Confirm connection status shows ACTIVE before running any workflows
Core Workflows
1. Send Templated Batch Emails
When to use: User wants to send templated emails to multiple recipients in one call
Tool sequence:
POSTMARK_LIST_TEMPLATES - Find available templates and their IDs [Prerequisite]POSTMARK_VALIDATE_TEMPLATE - Validate template with model data before sending [Optional]POSTMARK_SEND_BATCH_WITH_TEMPLATES - Send batch emails using a template [Required]
Key parameters:
TemplateId or TemplateAlias: Identifier for the template to useMessages: Array of message objects with From, To, TemplateModelTemplateModel: Key-value pairs matching template variables
Pitfalls:
- Maximum 500 messages per batch call
- Either
TemplateId or TemplateAlias is required, not both
TemplateModel keys must match template variable names exactly (case-sensitive)- Sender address must be a verified Sender Signature or from a verified domain
2. Manage Email Templates
When to use: User wants to create, edit, or inspect email templates
