# Lettr

Canonical: https://www.softwareadvice.co.nz/software/538182/Lettr

> Lettr is a transactional email platform for teams that want reliable sending without building and maintaining email infrastructure. It supports both HTTP API and SMTP relay, with real-time webhooks and analytics so you can monitor delivery and troubleshoot issues quickly.

Lettr is designed for how transactional email is maintained in the real world: developers set it up once, then templates evolve constantly. Instead of routing every small change through engineering, Lettr includes a visual template editor with version history and a draft/publish workflow. This lets product, design, and marketing teams update transactional templates safely, while engineers keep control over integration and data.

For operational visibility, Lettr provides lifecycle events (accepted, delivered, delayed, bounced, opened, clicked) and retained logs to help diagnose deliverability and rendering problems. Teams can stream events via webhooks, review sending activity, and trace what happened to specific messages.

Lettr also supports common template requirements such as dynamic placeholders, multi-language templates, and HTML import (useful for teams migrating existing templates or generating HTML elsewhere).

For deliverability and brand control, Lettr supports custom domains for tracking links and hosted assets, along with standard sending domain configuration. For larger senders, enterprise options include dedicated IP pools and custom rate limits.

Lettr is a good fit for SaaS products and product teams sending password resets, account notifications, receipts, onboarding sequences, and other lifecycle emails, where reliability matters and templates need to be editable without ongoing developer involvement.
