Before EmailQo, I was running outreach for my own agency, sending a few hundred cold emails a week trying to book calls." I was doing everything that was supposed to work — clean lists, personalized copy, decent subject lines — and reply rates still collapsed for weeks at a stretch. I eventually checked our sending domain and found it had been quietly blacklisted for over a month. Nobody tells you that. There's no dashboard for it. So I built EmailQo to be that dashboard: it checks SPF, DKIM and DMARC automatically and shows exactly what's broken, screens every email for spam triggers before you hit send, warms up new accounts on its own for two weeks before you rely on them, and paces sending so it looks like a person wrote and sent it, not a script. I started building it for my own team in April 2026, then realized almost every small agency and sales team had the exact same blind spot. It's still a small team based in Gurugram, India, and the whole product is built around one question: did this email actually land, and if not, why not.
