Frequently asked questions

Can the model send arbitrary emails?

Yes if granted the permission — which is why you want a scoped API key restricted to specific templates or IP pools for any non-development environment.

Does it support Event Webhook data?

The MCP server can fetch stats (opens/clicks/bounces) but does not itself host a webhook endpoint. Point webhooks elsewhere and read results from the stats API.

Can I use it with Twilio Email API for Marketing?

Yes — SendGrid Marketing Campaigns is accessible via the same v3 API under /marketing endpoints.
