# Mission Inbox review (2026): is it worth $50 a month? > Dedicated mailboxes and IPs for cold email sending Checked Nov 13, 2026 ยท graded Nov 13, 2026 by ToolGPA. Mission Inbox sells outbound email infrastructure: mailboxes on dedicated IP addresses, automatic DNS setup and a pre-send scan of content, headers and DNS. It is meant to sit under a sequencer or CRM the team already uses, such as Instantly, Smartlead, Apollo or HubSpot, instead of replacing it. - **Category:** Cold Outreach - **Made by:** Mission Inbox Inc - **Website:** https://www.missioninbox.com - **Runs on:** Web - **Who should skip it:** Not for you if you want to write or schedule campaigns, because there is no sequencer. - **Facts last checked:** Nov 13, 2026 ## Pricing As of Nov 13, 2026, Mission Inbox is a paid product, starting at $50 per month for 15 mailboxes and 5,000 sends. - **Pricing model:** Paid - **Free plan:** None. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Lite | $50 per month for 15 mailboxes and 5,000 sends | Dedicated IP addresses, MI Shield protection, analytics and sending logs.

Prices change, so confirm with Mission Inbox before buying. ## Ways to pay less - **17% off with annual billing** (Annual discount): The pricing page calculator lists an annual option at 17% off and a prepaid monthly option at 10% off, against pay-as-you-go monthly. Source: https://www.missioninbox.com/pricing ## Key features - **Dedicated IP addresses:** Each mailbox sends from IP addresses reserved for the account instead of a shared pool, so other senders' habits do not affect its reputation. - **MI Shield pre-send scan:** The vendor's own AI checks content, headers and DNS before each outbound send to catch problems before a campaign goes live. - **Automatic DNS and mailbox setup:** Mailboxes are created in one step and DNS records are configured automatically, so they can be connected to a sequencer afterwards. - **Cubes for separating clients:** Cubes split clients, brands and campaign workloads into separate sending environments, which matters for agencies. - **Premium warmup add-on:** Mailbox warmup is a paid add-on, billed in credits per mailbox. You can instead warm up with your own tool or skip warmup. - **API and SMTP access:** An API and SMTP sending give campaign or product email traffic its own sending reputation, with documentation linked from the site. ## Good for - Agencies that want separate sending setups for each client - Teams that already have a sequencer and only need mailboxes - Senders who want dedicated IPs rather than a shared pool ## Worth knowing - It is infrastructure only: there is no sequencer, so you need another tool to write and schedule campaigns. - Lite is a fixed plan with no overage billing; at 5,000 sends, counting warmup emails, you have to move to Scale. - Premium Warmups are a paid add-on, and sends include warmup emails. - Pricing is a monthly rate; the calculator shows prepaid-monthly (10% off) and annual (17% off) options. ## 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 $600 a year. - You could not: A network of real inboxes that open and answer your emails. - You could not: It plugs into other products, HubSpot, Salesforce and Apollo among them, and has an API. - You could not: AI features, unless you pay a model provider for each request yourself.
