Who is this for
If inbox placement is the bottleneck between send volume and revenue, this is the work.
Formula Inbox is built for B2B teams that depend on email to create pipeline.
We work with in-house growth and ops teams, and with agencies that need a specialist on the deliverability layer rather than another generic ESP playbook.
Engagements are tailored. Starting prices are a floor; scope depends on sending volume, infrastructure, and how much of the stack you want us to own.
Frequently Asked Questions
Yes. Formula Inbox works across virtually every major email service provider. Whether you send through a marketing platform, a cold-email tool, or a transactional ESP, we tailor DNS, warmup, and sending architecture to that stack rather than forcing a one-size-fits-all setup.
Most audits turn around in days, not weeks. We diagnose root causes across authentication, reputation, list quality, content, and infrastructure, with the full audit-and-remediation sequence typically landing inside 30 days.
That is a common path. Many clients start with an audit to pinpoint what is broken, then move into an infrastructure build and, when they want it held, a monthly retainer. The first call maps the right sequence and a combined quote.
No. The figures on this page are starting prices. Final scope depends on sending volume, the number of domains and IPs, your ESP, and whether you need a one-time project or ongoing coverage.
Continuous inbox placement monitoring, proactive reputation management, monthly reporting, a dedicated deliverability manager, and priority support. Every retainer is held to a 90%+ inbox placement benchmark, measured three months into the engagement.
