After your first send

• Authenticate your domain with SPF, DKIM, and DMARC.
• Open Analytics to inspect delivery records, or receive event webhooks.
• Manage bounces and complaints through suppressions.
• Use email validation to check contact addresses before sending.
• Configure sub-accounts when you manage sending for multiple customers.

Feature availability, retention, dedicated IPs, and support channels depend on your plan. See plans and billing before relying on a feature or trial.
