Inbox AI
InboxStack is an email deliverability intelligence platform built for teams who need to know why their emails aren't reaching the inbox โ not just that they aren't. At its core is Brain, a proprietary causal AI engine trained on a 22-year deliverability knowledge base, which correlates signals across your ESP, DNS authentication records (SPF, DKIM, DMARC), Google Postmaster Tools, Microsoft SNDS, and 50+ blocklists to pinpoint root causes instead of surfacing raw metrics.
Most deliverability tools stop at monitoring: they show you a drop in inbox placement or a blocklist hit and leave you to investigate. InboxStack goes further, tracing the actual causal chain โ a DKIM misalignment, a reputation dip on a specific sending IP, a content trigger โ so you can fix the real problem instead of guessing.
Setup takes minutes with no migration required: forward your email headers for an instant DNS/authentication audit, or connect your existing ESP and Postmaster accounts for ongoing monitoring. Optional seed testing gives you real inbox-vs-spam placement data across major providers.
Built for agencies managing multiple client domains and growing companies who've outgrown basic authentication checkers, InboxStack turns deliverability from a black box into a diagnosable, fixable system.

Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime.

Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / 13 days ago
The gateway is the web service that receives requests. I host it on Fly. It accepts Slack events, automation API calls, trigger requests, Composio webhooks, Inngest calls, and runtime calls. - Source: dev.to / about 1 month ago
The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / about 2 months ago
Three independent encryption layers at rest: client-side E2E, Cloak AES-256-GCM in Postgres, and LUKS disk encryption on Fly.io. - Source: dev.to / 3 months ago
