What is Inboxing
Inboxing provisions ready-to-send email inboxes at scale with minimal manual work. Each domain receives 49 pre-configured mailboxes designed for cold outreach. The platform handles DNS records, compliance checks, and mailbox creation in a few hours.
Overview
Inboxing automates the process of creating and configuring large blocks of email inboxes across multiple domains. Each domain gets 49 individual mailboxes, all set up with proper DNS configuration and deliverability safeguards. The platform supports anywhere from a single domain up to 1,500 domains, making it suitable for growing outbound programs. Users can submit setup jobs through a web interface or API, then begin sending within one to two hours. Daily sending capacity is capped at 250 emails per domain to maintain strong inbox placement rates. This tool is built for cold outreach workflows, not high-volume marketing blasts.
How to use Inboxing
Teams submit a domain setup request through the dashboard or API, then update nameservers to point to the platform. Within a couple of hours, all 49 inboxes per domain are live and ready for outbound campaigns. Users upload a CSV of contacts and begin sending through their preferred email platform.
