Experts in the part of email nobody else owns.
InboxGenius is an email deliverability firm. Not a marketing agency with a deliverability service — a practice built entirely around how mail behaves on the network, and what to do when receiving systems stop trusting it.
How the company got here
Deliverability consulting
InboxGenius started as an email deliverability consulting firm, working with senders on reputation, authentication, infrastructure and inbox placement.
Cold email as a service
We developed deep expertise in cold email systems, and today run cold email lead generation as a managed service rather than building systems for others to operate.
Managed postmaster services
Larger organizations needed something more permanent than advice: an ongoing expert function accountable for how their email behaves. That became the flagship service.
Working globally
InboxGenius works with companies around the world, across B2B and B2C sending, on marketing, transactional, application, alert and notification flows.
How we work
Four things shape every engagement. They also explain the kind of client we're a good fit for — and the kind we're not.
Experts, not generalists
Deliverability and postmaster operations are the whole business. Our consultants have direct access to, or established working relationships with, major postmaster teams and email ecosystem stakeholders — including Google, Microsoft, Yahoo and other networks worldwide.
Retained, not hourly
We work on a monthly retainer. Deliverability is continuous, and an expert who already knows your environment is worth more in an incident than one starting from zero.
Advocacy, not just advice
When something needs escalating, we prepare the case and raise it on your behalf rather than handing you a document and wishing you luck.
Precise about what we can promise
Nobody can guarantee inbox placement or delivery, and anyone who says otherwise is selling something. We commit to expertise, engagement, escalation and remediation — and we're clear about the limits.
Email is infrastructure. It deserves someone whose job is only that.
If your organization depends on email arriving — and has nobody whose remit is making sure it does — that gap is what InboxGenius exists to fill.
Start with a conversation.
No pitch deck. An expert, your infrastructure, and an honest read on what's happening to your email.
