Mission Inbox

Mission Inbox (operating at missioninbox.com) is a B2B email infrastructure and deliverability platform engineered for businesses prioritizing outbound communication. Founded in 2024 by Anthony Baltodano and Steve Baltodano and headquartered in San Francisco, California, Mission Inbox eliminates the need for companies to manage complex email-sending servers or rely on unreliable hacks like Gmail workarounds. Under the hood, the platform provides isolated, AI-protected sending environments—dubbed ‘cubes’—with dedicated IPs, ensuring higher deliverability rates for sales, marketing, and transactional emails. This allows sales and marketing teams to scale their outreach without risking blacklisting or inbox placement issues. Mission Inbox remains fully bootstrapped, having never raised external funding despite achieving a $25M valuation through deliverability innovation.
