Connect an email provider

Connect a workspace email provider in Settings → Email. 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.
