[Description](#description)[Use cases](#use-cases)[Features](#features)[Pricing](#pricing)[Integrations](#integrations)[Support](#support) Lettr ## What is Lettr? Lettr is a transactional email platform for teams that want reliable sending without building and maintaining email infrastructure. Send via HTTP API or SMTP relay, track delivery and engagement with real-time events (delivered, bounced, delayed, opened, clicked), and debug issues with searchable logs and webhooks. Lettr combines infrastructure with team workflow: developers integrate once, then product/design/marketing can manage transactional templates in a visual editor with version history and a draft/publish workflow—so routine edits don’t require dev tickets or redeploys. Lettr supports dynamic placeholders, HTML import, and multi-language templates. For deliverability and brand control, Lettr supports custom domains for tracking links and hosted assets, plus standard sending domain configuration. Enterprise options include dedicated IP pools and custom rate limits. ## What is Lettr used for?
