We built TrulyInbox because we kept watching great cold outreach fail for the dumbest reason: the emails never made it to the inbox. Not because the copy was bad. Not because the offer was weak. Because new mailboxes send from unknown domains, ISPs treat them as suspicious, and everything ends up in spam or promotions. Warmup tools solved this a while back, but they charged per inbox. If you added mailboxes to your outbound, your warmup bill scaled linearly. We wanted a tool where teams could add as many mailboxes as they needed without their deliverability tool becoming their biggest cost. So TrulyInbox is built around three things: - Unlimited email accounts on every plan. You pay by daily warmup volume, not per mailbox. - AI-generated warmup content for 50+ industries in 12 languages, so warmup emails read like real conversations, not templated filler. - Real deliverability intelligence: Daily Deliverability Score, ESP-level placement (Google, Microsoft, and 18+ others), and an Outreach Readiness indicator that tells you exactly when a mailbox is safe to send from. We're seeing 95%+ inbox placement in production, backed by a network of 40,000+ real warming accounts sending 500,000+ warmup emails per day. Free plan available if you want to try it before committing. Paid plans start at $22/month, unlimited mailboxes included on every tier.
