The site lists Instantly, Smartlead, Apollo, Lemlist, Reply.io and Bison. - **Unlimited replacement inboxes:** Both plans include replacement inboxes when one is lost or flagged, with a priority queue on the higher plan. - **Slack support channel:** The higher plan adds a dedicated Slack channel and account manager, and the site says the founder joins customer channels. - **Infrastructure calculator:** A calculator turns a daily send volume into a number of inboxes, domains and a monthly cost. ## Good for - Agencies that want mailboxes built for them rather than DIY - Teams that want official Google or Microsoft accounts - Senders who prefer per-inbox pricing with no contract ## Worth knowing - You supply the domains; the site does not list domain purchase in the price. - Both plans start with a minimum order of 30 inboxes. - It provides mailboxes only; you need a separate sequencer to send campaigns. - Account manager, Slack channel and 24-hour monitoring come only with the $4.50 tier. ## ToolGPA grades **GPA: 1.6 out of 4**, graded Nov 13, 2026.

That is not a weekend's work, with an AI app builder or without one. That makes this kind of software worth paying for, not this one in particular: 64 of the 81 other cold outreach tools grade higher. It costs $42 a year. - You could not: A network of real inboxes that open and answer your emails. - You could not: Reading the reports inbox providers send about your domain. - You could not: It plugs into other products, Instantly, Smartlead and Apollo among them.
