Email (SendGrid)

Overview

The SendGrid events extension sends transactional email through the Twilio SendGrid Mail Send API. Use it for worker-initiated notifications such as confirmations, reports, escalation emails, and summaries.

This pack is for outbound email delivery. If you need incoming email events, use a webhook-capable pack with SendGrid Inbound Parse or a custom email event extension.

Delivery Notes

SendGrid dynamic templates use a template_id and dynamic_template_data.
Attachment content is sent as base64-encoded data with a MIME type.
Use SendGrid sender authentication and narrow API key scopes for production workers.
