Founding Marketer

Mission Inbox is the infrastructure layer for B2B email at scale. We provide dedicated-IP sending infrastructure, automated DNS authentication, pre-send compliance scanning, and reputation management for B2B sales teams, agencies, and SaaS companies that depend on email deliverability as a core business function.

We are at an inflection point. The product is built, revenue is growing, and the customer base is expanding. What we don't have yet is a marketing engine. That's the gap this role is hired to close — from zero.

This is not a "run our marketing" role. There is no existing playbook to execute, no team to manage, and no agency doing the heavy lifting. You will be the first dedicated marketing hire at Mission Inbox . You will build the strategy, own the execution, and eventually manage the team as channels mature and headcount follows performance.
