TrulyInbox

TrulyInbox is an email warmup and deliverability platform built for B2B teams running cold outreach at scale. It gradually warms up email accounts by sending and receiving realistic interactions across a network of real inboxes, building sender reputation with Gmail, Outlook and other providers before live campaigns begin.

How It Works

The platform connects to existing email accounts (Gmail, Outlook, Zoho Mail, SendGrid and 18+ providers), then automates warmup interactions, including opens, replies, and spam folder rescues, to train inbox providers that the sender is legitimate. Users set warmup volume, ramp speed and reply rates per account, then monitor inbox placement through a central dashboard.

Who It Is For

Lead generation agencies, SDR teams and founder-led sales teams managing anywhere from 5 to 50+ mailboxes. The volume-based pricing model with unlimited email accounts makes it particularly cost-effective for teams scaling outbound, compared to per-inbox alternatives where costs multiply with every new mailbox.

Key Differentiators

• Native integration with Saleshandy for one-click mailbox imports
• Open API available from the Starter plan for custom workflows
• Dashboard-level visibility into warmup progress, reply rates and inbox placement across all connected accounts
