AutoSend

AutoSend is a modern email platform designed for developers, marketers, and AI agents to send transactional and marketing emails with high deliverability and fast inbox placement. Built by the team behind Peerlist, AutoSend offers a clean interface, intuitive workflows, and volume-based pricing that rewards growth rather than penalizing large contact lists.

The platform delivers emails within seconds, making it ideal for time-sensitive transactional messages like OTPs, password resets, and order confirmations. With over 2 million emails sent weekly, AutoSend provides both REST API and SMTP integration options for seamless connectivity with any tech stack.

• RESTful Email API provides a simple, powerful interface to send emails with a single API call, offering full control over headers, attachments, and delivery with official SDKs for Node, Python, PHP, Ruby, Go, and more.

• Marketing Campaigns enables creating, personalizing, and sending beautiful marketing emails to targeted audiences with newsletters, product launches, and promotional content that converts.

• Email Automations allows building welcome sequences, onboarding flows, and re-engagement campaigns that send automatically to the right people at the right moment.

• Global Email Validation and Suppression Engine validates every contact and suppresses risky ones before sending, automatically blocking spam traps, disposable addresses, and invalid emails to protect sender reputation.

• Real-time Activity Logs provide detailed tracking for every email with filtering, searching, and debugging capabilities to know exactly what happened to each message.

• Email Builder offers a Notion-like block editor for non-technical users plus HTML editor and ReactEmail support for developers, enabling email creation without coding knowledge.

• Analytics & Insights displays opens, clicks, and conversions in real-time, helping identify what works and apply learnings to future campaigns.

• Webhooks enable event-driven workflows with real-time tracking of delivery, opens, clicks, bounces, and unsubscribes.

To get started, sign up for an account, configure your sending domain with SPF, DKIM, and DMARC authentication, and begin sending emails via API or SMTP. Easy migration tools allow instant import of templates, contacts, and automations from Resend, SendGrid, Loops, and other providers with zero downtime.
