About
Coldletter is an email templating and automation platform built for product and engineering teams that need better control over the emails their applications send. The platform works on top of providers such as SendGrid, Postmark, Amazon SES, Mailgun, Resend, and SparkPost, allowing teams to keep their existing delivery stack. Users can design responsive, accessible, and dark-mode-safe email templates with a visual editor instead of hand-coding complex HTML or MJML. Coldletter also supports reusable blocks, typed variables, live previews, test sends, localization, version control, and approval workflows. Its automation tools let teams build email journeys with triggers, waits, branches, A/B testing, and delivery analytics. Coldletter helps teams design, automate, manage, and deliver product emails more reliably from one centralized workspace.
