Native CRM integrations with HubSpot and Salesforce allow running outbound campaigns directly from existing CRM workflows

Native multi-channel capabilities combining email, LinkedIn, calls, and SMS in single automated sequences without third-party tools
OAuth support for Gmail and Exchange simplifies email account connection and reduces authentication friction
Advanced contact status management and stage tracking with bulk operations for efficient workflow automation
No native SDKs provided, requiring developers to build custom HTTP clients for complex integrations
Rate limits not publicly documented, making it difficult to plan high-volume API implementations
LinkedIn automation features carry inherent platform risk and may violate LinkedIn terms of service
