The platform offers marketing campaigns for creating, personalizing, and sending beautiful emails to the right audience. It includes email automations for welcome sequences, onboarding flows, and re-engagement campaigns. Analytics and insights provide real-time metrics on opens, clicks, and conversions. An email builder allows users to write emails in markdown and preview them instantly.

AutoSend provides REST APIs with comprehensive SDKs for Node, Python, PHP, Ruby, Go, and other languages. It supports webhooks for event-driven workflows, SMTP for legacy systems, and offers real-time logs for debugging. The platform includes easy migration tools to import templates, contacts, and automations from services like Resend, SendGrid, and Loops.

Benefits include quick setup with zero downtime guarantees, volume-based pricing that only charges for emails sent rather than stored contacts, and a clean interface designed for usability. The platform achieves consistent performance metrics including 98.97% deliverability rate and 1.08% bounce rate.
