Klaviyo Deliverability for DTC
We audit and fix the Klaviyo deliverability problems your team can't see — so your flows stop leaking revenue into the spam folder. Built by operators who ran email at $100M+ scale, not agency consultants.
The Problem
Klaviyo's UI shows delivered — it doesn't show reached the inbox. Brands blame creative, fatigue, or cadence when the real culprit is deliverability infrastructure.
DMARC sits at p=none (or is missing). SPF and DKIM alignment quietly fail. ISPs downgrade every send.
Disengaged segments stay in the cadence. Sender reputation takes the hit. Klaviyo never flags it.
A $5M beauty brand on Klaviyo with 250K contacts typically loses $25K–$45K per month to spam placement and flow gaps.
Email is treated as a marketing cost center instead of the most profitable revenue channel. Sender reputation damage compounds: the longer it's ignored, the more expensive it is to repair, dependency on paid channels rises, and CAC climbs.

Why Us
Most deliverability consultants are specialists who've never been the executive on the hook for email P&L. That's a different conversation — and a different outcome.
Founded by an operator who built and ran email deliverability as COO at high-volume B2C media and marketplace businesses — 50B+ emails, $100M+ in email revenue managed at operator scale — before founding Optimal Inbox for DTC brands on Klaviyo.
$2,500 flat for the Klaviyo Revenue Audit, delivered in 2 weeks. Tiered managed retainer at $3K–$7K per month, published up-front. Transparency competitors can't match without restructuring their business.
We don't do B2B cold outreach, SaaS, or ESP migrations. We do one thing: get your Klaviyo program to outperform its category benchmark.
What's Included — Tier 1
Read-only Klaviyo access. Five workstreams. Delivered as a 30–50 page report, a 60-minute walkthrough, and a 90-day remediation roadmap.
Meet the Founder
Spencer built and ran email operations as COO at high-volume B2C media and job-marketplace businesses — managing 50B+ emails and $100M+ in email revenue before founding Optimal Inbox. Operator-side pattern recognition: the person on the hook for email P&L at the board level, now running audits for DTC founders on Klaviyo.
We don't claim proprietary methodology, direct relationships at Gmail / Microsoft / Yahoo, or a client book of 65+ named DTC brands — none of those are currently true. The honest story is stronger than the overclaimed one.
FAQ
Your team is great at campaigns — we handle the infrastructure layer they don’t have bandwidth or expertise for. Deliverability is a specialty, not a generalist skill. We work alongside your team, not instead of them.
ESPs provide shared infrastructure and basic monitoring. When you’re leaving revenue on the table because 20%+ of your emails hit spam, you need dedicated expertise — not a support ticket to a platform that serves thousands of other senders on the same IPs.
Most agencies manage campaigns — creative, copy, sends. We manage the infrastructure underneath: sender reputation, IP warming, authentication, inbox placement optimization. They decide what to send; we make sure it gets delivered.
Two weeks from the moment you grant read-only Klaviyo access. You receive a 30–50 page written report, a 60-minute walkthrough call, and a 90-day prioritized remediation roadmap. The price is flat at $2,500 and published publicly — no custom quotes, no discovery-call pricing dance.
Read-only. We don’t modify your account during the audit — we review suppressions, flow performance, segments, and revenue attribution, then deliver the remediation roadmap for your team (or ours, under Tier 2) to execute. You revoke access whenever you want.
No. The Tier 1 audit is a complete, standalone engagement — you walk away with a full roadmap you can execute in-house or hand to your existing agency. If you do choose to engage us on Tier 2 within 30 days, your $2,500 audit fee credits toward month one of the retainer.
