Autowarm – Internal Tools for SaaS at Scale
From inbox rotation to AI reply tracking — how we powered Autowarm's backend launch.

Autowarm (Email Deliverability SaaS)
Problem
As Autowarm scaled, the team was juggling inbox validation, warmup tracking, and account health scoring manually. This slowed support, onboarding, and feature releases.
Solution
We stepped in as backend partners and built:
- Real-time warm-up tracking dashboard (deliverability %, inbox status, blacklist check)
- Auto-alerts for failing inboxes
- Internal tools for bulk inbox verification and user scoring
- Scripts for simulating smart replies and human open rates
Impact
- 🔁 Inbox rotation enabled for 500+ users
- 🧑💻 Support dependency dropped by 70%
- 🚀 4 internal tools shipped in < 2 weeks

What We Loved
It wasn't "dev-for-hire" — we operated like product owners, helping ship faster and think through scaling logic.
