The default provider sends both campaigns and transactional workspace messages. ## Prepare your sender An administrator can connect Brevo, Resend or SendGrid. Create a provider account and verify your sending address or domain using that provider’s instructions. Check its current prices and sending limits directly; Stacks does not set those limits. ## Connect Choose Connect on the provider card. Enter its API key, verified From email and From name, plus any requested webhook signing secret. Save & connect stores encrypted credentials and selects the default sender. A saved connection alone does not prove sending works. ## Check delivery and event tracking Send a test from this page and check its result and the receiving inbox. Provider acceptance is not inbox delivery. Follow any setup warning or manual webhook instructions; bounce and complaint suppression needs correctly configured, authenticated event tracking. ## Enable notifications Use Enable email notifications for transactional messages, and Settings → Email Alerts to choose events. There is no separate legacy SendGrid-only setup required for these workspace messages. Platform login and registration mail have separate operator configuration. ## Check your domain Settings → Deliverability checks DNS. Use the actual records supplied by your provider. A passing check cannot guarantee inbox placement. Keep API keys and signing secrets private. ## Official provider instructions - [SendGrid API keys](https://www.twilio.com/docs/sendgrid/ui/account-and-settings/api-keys) - [SendGrid sender identity](https://www.twilio.com/docs/sendgrid/for-developers/sending-email/sender-identity) - [Signed event webhooks](https://www.twilio.com/docs/sendgrid/for-developers/tracking-events/getting-started-event-webhook-security-features) Reviewed against the application on September 11, 2026.
