## What you can do here Add a provider with its credentials, **test** it, set one as default, enable or disable providers. Creating an integration does not send anything by itself — it makes the provider available to templates, campaigns, and triggers. Editing a saved integration also shows a **domain health** panel that checks the DKIM, SPF and DMARC DNS records of your sender domain. ## Example: connecting Twilio SendGrid Pick the provider, name the integration, and fill its credentials — for SendGrid that is the API key and the verified sender:

After **Save** the integration appears with its full action set — **Set as default**, **Disable**, **Test**, links to the provider's documentation and to the SDK/API docs, and **Delete**:

**Test** sends a real probe through the provider — run it once after saving to confirm the credentials work before any template or campaign relies on this integration. ## Use it from code [Notifications → Email](/sdks-and-cli/notifications/email.md). ## API reference Endpoints: [Get Email Integrations](/api-reference/notifications/email/get-email-integrations.md), [Save Email Integration](/api-reference/notifications/email/save-email-integration.md), [Test Email Integration](/api-reference/notifications/email/test-email-integration.md), [Check Email Integration Domain Health](/api-reference/notifications/email/check-email-integration-domain-health.md).
