Description
Coldletter is an email design and automation layer that helps teams create, manage, and send product emails without replacing their existing email provider. It connects with delivery services such as SendGrid, Postmark, Amazon SES, Mailgun, Resend, and SparkPost, giving companies flexibility while keeping sending infrastructure intact. The platform includes a visual editor where teams can build templates, add variables, reuse blocks, and preview emails across clients such as Gmail, Outlook, and Apple Mail. Every template is designed to be responsive, accessible, and safe for dark mode by default. Developers can trigger templates through a single API request while Coldletter handles rendering, data merging, routing, retries, suppression, and idempotency. Marketing, lifecycle, design, and product teams can use the platform to manage email content without constantly relying on engineering for every change. Journey automation tools allow users to create workflows based on events, schedules, engagement, attributes, or A/B testing paths. Version control, template diffs, rollbacks, localization, test sends, roles, approvals, and analytics help teams manage production emails with more confidence. Coldletter gives organizations a structured way to build polished product emails while improving collaboration between technical and non-technical teams.
