What is Coldletter?

Coldletter is a product email platform that combines visual email design, template management, automation, and developer-friendly delivery workflows in one workspace. The platform is built to sit on top of existing sending providers, including SendGrid, Postmark, Amazon SES, Mailgun, Resend, and SparkPost. This allows teams to improve how emails are created and managed while continuing to rely on trusted providers for actual delivery. Coldletter’s editor lets users design emails like documents, using drag-and-drop blocks, reusable partials, typed variables, and real-time previews. Templates are built to be responsive, accessible, and dark-mode-safe, reducing the need for manual table-based HTML or MJML workarounds. Developers can send any template with one API call while Coldletter merges customer data, renders the email, chooses the configured route, and handles delivery safeguards. The platform also includes automation journeys with triggers, delays, branching logic, A/B testing, and scheduled sends. Teams can manage template versions like code, review diffs, roll back changes, run test sends, and require approvals before updates reach production. Localization features allow companies to create translated template variants that resolve automatically at send time. Unified analytics help teams track opens, clicks, bounces, and deliverability across multiple providers. Coldletter helps product, lifecycle, design, and engineering teams create better emails faster while keeping delivery reliable and workflows organized.
