Unleash your AI agent over Twilio SendGrid's trusted enterprise email platform. Transform your chat interface into a fully-fledged communications command center. By implementing this MCP server, your LLM gains the power to investigate unaddressed hard bounces, dispatch highly contextual custom emails, and automatically organize sprawling marketing directories.

What you can do

  • Live Email Dispatching — Dictate a tailored email to your agent and order it to use dispatch_email to send fully authenticated outbound HTML campaigns
  • Bounces & Suppression Auditing — Ask the AI to identify why recent deliveries failed using list_bounces and tell it to permanently pardon specific addresses via delete_bounce
  • Dynamic Template Inspection — Fetch all your stored transaction shells (list_dynamic_templates) and inspect precise structure iterations to verify UI before broadcasting
  • CRM Growth Automation — Continuously append or enrich subscriber details straight from conversational prompts by executing create_marketing_contact on the fly

How it works

  1. Enable the targeted server component inside your client environment
  2. Supply your encrypted SendGrid API Key bearing adequate sub-user permissions
  3. Engage Cursor or Claude organically to query unsubscriptions or force send notifications immediately

Who is this for?

  • Customer Success Managers — organically instruct your AI to search for an angry customer's email across 'bounces', 'spam', or 'unsubscribes' to verify deliverability
  • Software Devs — test specific edge-cases of dynamic templates bypassing Postman UI just by asking Claude to shoot a trial template straight to your inbox
  • Marketing Integrators — query the global subscriber list numbers daily alongside other metrics completely through chat

Using the SendGrid API, list emails that have bounced recently to audit our hygiene.

I've invoked `list_bounces` spanning your latest transmissions. You have exactly 4 hard-bounced targets stored within suppression parameters. For instance, 'hello@fake-email-z.com' returned an error string: 550 Relay Denied. Do you want me to automatically execute the `delete_bounce` directive on any specific valid records to unblock them?

Dispatch an HTML email from 'marketing@mybrand.com' to 'client@test.com' with subject 'Special Delivery'. Use standard <h1>.

The transmission has been completed effectively. The `dispatch_email` tool received identical constraints, leveraging 'marketing@mybrand.com'. The SendGrid HTTP payload accepted your outbound message synchronously and queued it upon the global outgoing rail successfully.

Audit the Dynamic Transactional Templates list. Summarize findings.

I've engaged `list_dynamic_templates` surveying your internal dashboard environment. Your vault holds 7 different distinct design layouts. The most recently updated is the 'Welcome Onboarding Form' attached to template ID (d-f018x8axxx...). Would you like me to dive into `get_template_details` for that specific iteration to reverse-engineer its internal blocks?

Yes. The integration natively wraps the `dispatch_email` mutation tool. If adequately prompted, the system will formulate HTML payloads and broadcast them assuming you explicitly provide the verified Sender Identity (from_email) corresponding to your account.
