We believe in building in public. Here's what's on the roadmap for Q3, what we've already shipped, and what we're thinking about for Q4.
Already shipped
- Core SMTP receive — inbound email → webhook in under 500ms on average
- Thread detection — automatic conversation threading via In-Reply-To / References headers
- Multi-tenancy — organizations with isolated API keys
- Dead-letter queue — inspect and replay failed webhook deliveries
- Docker Compose self-host — single command to run the full stack
In progress
Streaming delivery (WebSockets) — For latency-sensitive use cases, we're adding a WebSocket endpoint that pushes message events in real time. No polling, no webhooks, sub-100ms delivery.
Attachment storage — Right now attachments are included inline in the webhook payload (Base64 encoded). We're moving them to a separate blob storage layer with signed URLs.
SaaS launch — The managed version of Programmable Inbox is our top priority for Q3. We'll launch with a usage-based free tier (5,000 messages/month) and paid plans above that.
Planned for Q4
- Replay from timestamp — reprocess all messages from a given time window, useful for recovering from bugs in your webhook handler
- Email sending — we're email receive focused today, but outbound is on the roadmap
- SDK libraries — typed clients for Node.js, Python, and Go
- Zapier / Make integration — no-code routing for non-developer users
How to influence the roadmap
All of our roadmap is tracked publicly on GitHub. Open an issue, upvote an existing one, or start a Discussion. We read everything and it directly influences what we build next.
