Premium Inboxes is a cold email infrastructure tool that lets you set up sending infrastructure hands off, human verified, and with white glove integration. You choose Google Workspace or a Microsoft 365 account — a common approach is to diversify roughly 70 percent Google Workspace and 30 percent Microsoft 365.
Premium Inboxes' infrastructure is officially US based. That matters because sending from India-based infrastructure to US inboxes is one of the fastest ways to hurt deliverability. Setup, DNS, and account diversification are all handled on their end so campaigns stay stable.
Pricing starts at $3.5 per inbox, billed per inbox with no unnecessary commitments. If you're sending over 1,000 emails a day, or 30,000 a month, you can move up to the Growth or Enterprise plan.
Premium Inboxes has more than 2,000 customers, setup within six hours once onboarding is complete, and a 5.0 rating from 510+ Trustpilot reviews, and is well regarded in the cold email space. It's built mainly for agency owners who want safe, stable, long-term campaigns. If you'd rather manage your own infrastructure, Maildoso and Zapmail are strong self-managed alternatives.
