  "summary": "SendGrid is automatable today through the Twilio SendGrid v3 REST API. This record is SendGrid email. It is not the Twilio communications products recorded separately, and it is not Resend, Postmark, or Mailgun. The host is https://api.sendgrid.com/v3/. Authenticate with Authorization Bearer and an API key created in the account. Keys can carry permissions that limit which account areas they can access. Official SDKs cover C#, Go, Java, Node.js, PHP, Python, and Ruby. The reference covers mail send, templates, contacts, suppressions, and event webhooks. The Event Webhook posts deliverability events such as delivered and bounced, and engagement events such as open and click. A third-party stdio server at github.com/coopersully/sendgrid-mcp, pushed on 2026-09-29, calls v3 with SENDGRID_API_KEY for templates, contacts, sends, and suppressions. It is not a Twilio repository. Twilio hosts a read-only docs MCP at https://mcp.twilio.com/docs that indexes SendGrid documentation and does not execute API calls. The opened product list on that page does not name SendGrid among indexed APIs. That does not establish the absence of a SendGrid operations server, so first-party MCP stays unknown. No SendGrid CLI was established on the opened pages. iPaaS catalogs were not opened. Computer-use viability is unassessed. API scores 8 and is the best path. The one maintained community server scores 4.\n"
