Overview
Agent safety: Always confirm recipients, subject, and content with the user before sending. Email is irreversible once delivered. Never send email autonomously without explicit user approval — especially for batch sends to multiple recipients.
Twilio Email is a separate product from SendGrid. Both send email, but they use different APIs, credentials, templating languages, and endpoints. If you have a SendGrid API key (SG.-prefix), use twilio-sendgrid-email-send instead.
