Email Infrastructure for Modern Product Teams

Visit Keplars

Keplars is an email infrastructure platform that simplifies sending transactional and marketing emails for product teams. It addresses the complexity of traditional email setup—such as configuring SPF, DKIM, DMARC, and SMTP—by allowing users to send emails through Gmail, Outlook, or custom domains using secure OAuth, without DNS configuration. The platform provides a unified solution for building, sending, testing, tracking, and scaling customer emails.

Key features include a unified email editor with drag-and-drop and raw code capabilities, real-time delivery tracking for opens, clicks, and bounces, and sandbox testing for safe previews. It offers REST API, SMTP relay, webhooks, and SDKs for integration, along with over 100 native integrations with tools like Zapier, n8n, and Vercel. Additional capabilities include mailbox warmup, marketing campaign management, and AI-powered templates. The platform supports SPF, DKIM, and DMARC authentication and provides 99.99% uptime SLA with multi-region failover.

Keplars is designed for developers, startups, and growing businesses. It offers a 7-day free trial with no credit card required, and plans include round-the-clock expert support. Pricing is available on request, and the platform is built for scale with enterprise-grade deliverability and security measures.
