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.

  • How to Validate a SaaS Idea With No Money
    The free stack: Carrd has a free tier that handles a one-page site fine, or throw plain HTML on any free subdomain you already have access to. For the form, Google Forms is free forever, and Tally's free tier embeds cleanly if you want it to look less like a survey. Wire the CTA to the form, and you have a functioning validation machine for exactly $0. - Source: dev.to / 10 days ago
  • Just launched my dating advice blog built with Next.js - feedback welcome!
    It started as a personal dating profile builder (kind of like a Carrd for dating) but after concerns around privacy, scope creep, and some brutally honest Reddit feedback (quoting, "it's cringe, you should delete it and never mention it again"), I pivoted to focus on a dating advice blog instead. - Source: dev.to / about 1 year ago
