Developer & Integration Documentation
Smartlead is built with an API-first architecture, making it suitable for teams that need to integrate cold email workflows into broader sales or data pipelines.
Key technical integration points:
- REST API — programmatic access to core platform functionality
- Webhooks — event-driven notifications to sync Smartlead activity with external systems in real time
- Native integrations — pre-built connectors for Google (Gmail / Google Workspace) and Microsoft Outlook
- White-label API access — agencies can embed and rebrand Smartlead's capabilities within their own platforms
Infrastructure notes:
- Supports unlimited mailboxes, allowing horizontal scaling of sending infrastructure without platform-imposed limits
- Built-in email warm-up and sender reputation management operate at the infrastructure level, reducing deliverability overhead for engineering teams
- SmartAgents provide AI-driven automation layers that can be incorporated into outreach sequences
Refer to Smartlead's official API documentation for endpoint references, authentication details, webhook payload schemas, and rate limits.
