# Postmark MCP for AI Agents AI Agent Connect > Postmark MCP for AI Agents. Automate transactional emails, manage templates, and check bounce logs from your AI client. ## Overview - **Category:** email-marketing - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_NXSEhZled0Vu4GkrCevS3cBuGGJbkuDDQGembvq6/ai-agent-connect - **Tags:** transactional-email, email-delivery, template-management, bounce-tracking, api-integration ## Description You can now handle your entire transactional email pipeline without leaving your AI client. Instead of jumping between tabs to check why a specific user didn't get a password reset, you can just ask your agent to look up the bounce log. If you need to double-check a template's HTML before a big launch, you can pull the raw body directly into your chat. This Connector gives your agent the eyes to see your delivery health and the hands to send out custom messages. It's part of the Vinkius catalog, making it easy to plug into your existing workflow so you can focus on shipping code rather than hunting down delivery errors. ## Tools ### get_delivery_stats Get email delivery statistics ### get_outbound_stats Get outbound delivery stats ### get_template Retrieve the raw body and details of a specific email template. Use this to verify your HTML and variables. ### list_bounces List recent email bounces ### list_domains List all verified sending domains ### list_outbound_messages List sent messages ### list_account_servers List account servers ### list_email_templates List email templates ### send_batch_email Send emails in batch ### send_email Dispatch a transactional email using a subject line and either plain text or HTML. Use this for one-off messages. ### get_server_info Get Postmark server configuration ## Prompt Examples **Prompt:** ``` Check the bouncing metrics for our transactional emails. ``` **Response:** ``` I've analyzed your bounce metrics. The delivery logs show 14 Hard Bounces and 3 Soft Bounces within the query scope. Overall health looks good! Want me to list the specific emails? ``` **Prompt:** ``` Can you fetch the HTML body layout of our 'Welcome' template? ``` **Response:** ``` I found your 'Welcome' template (ID: 809214). It expects three variables: `first_name`, `action_url`, and `support_email`. The HTML renders a classic logo-centric email layout. ``` **Prompt:** ``` Send a standard test email to alice@example.com using our current Postmark setup. ``` **Response:** ``` The email has been processed! Postmark returned success mapping with a Message ID `f8a847a9-2169-45e0-...` indicating instantaneous dispatch. ``` ## Capabilities ### Send transactional emails Dispatch messages using raw HTML or your pre-configured templates. ### Audit bounce logs Filter through hard and soft bounces to find specific failed deliveries. ### Inspect template HTML Fetch the raw body of any template to verify your dynamic variables. ### Monitor delivery health Get a high-level view of your outbound message streams and open rates. ### Manage account details Pull specific account details and list all active templates at once. ## Use Cases ### Debugging a broken signup flow An engineer asks the agent to find a specific bounce for a user who didn't receive a verification link. ### Verifying a Welcome email A product manager asks the agent to pull the HTML body of a template to check for broken links. ### Checking daily delivery stats A system admin asks for an overview of outbound messages to see if there's a spike in errors. ### Sending a quick test A developer asks the agent to send a raw HTML test email to a staging environment. ## Benefits - Faster debugging: Find out exactly why an email failed to deliver without leaving your code editor. - Instant layout verification: Pull template HTML into your chat to ensure variables align with your backend code. - Rapid testing: Send test emails to any address immediately to confirm your triggers are working. - Real-time health checks: See your outbound metrics and bounce rates in a summary format during your workflow. - Reduced context switching: Manage your entire email pipeline from one chat interface instead of multiple browser tabs. ## How It Works The bottom line is you get a direct line to your email infrastructure from your chat window. 1.

Once you connect it through Vinkius, your agent can start managing your emails. **Can I use this server to actually send operational emails from my account?** Yes! The `send_email` and `send_email_with_template` tools will dispatch active live emails using your Postmark server configuration. **How can I debug a specific user reporting that they didn't receive an email?** You can ask the agent to execute `search_outbound_messages` or `search_bounces` using their exact email address. The agent will fetch the delivery log and status codes. **Do I need the Account Token or the Server Token to use this?** You only need the **Server Token**. Postmark divides workflows by servers (environments). Supplying the server token isolates this specific operational environment perfectly. **Can I send a transactional email using my AI agent?** Yes! Use the `send_email` action. Provide the sender and recipient details along with your subject and message body.
