Since Klaviyo switched to billing for every active profile — not just the people you actually email — the average store pays for thousands of contacts who haven't opened, clicked or bought in 6+ months. Deadweight finds them. You approve. Your bill drops a tier.
Free. Read-only. We reply with one number: what you're overpaying per month.
That's $1,200/yr back — for a tool that costs $19/mo.

Tier prices are estimates interpolated from Klaviyo's published email plans (2026). Your audit uses your exact numbers. Suppressed profiles are officially non-billable per Klaviyo's own docs.
A scoped Klaviyo API key. We build the same "inactive 180+ days" segment Klaviyo's own help docs recommend — created 6+ months ago, received your emails, never opened, never clicked, never bought.
Full preview and CSV export before anything happens. Exclude VIPs, recent signups, recent buyers. Optionally run a last-chance sunset email first — we wait, then act.
One click suppresses the segment (suppress ≠ delete: data stays, billing stops). Then the part everyone misses: Klaviyo never downgrades your tier automatically. Deadweight watches your billable count and tells you the moment your plan doesn't match it.
Suppression is reversible. Profiles aren't deleted — Klaviyo keeps every order and event. One click un-suppresses. We never touch anyone who opened, clicked or bought within your chosen window.
These are people who received 6+ months of your emails and never once engaged. Sending to them costs you money twice: on your bill, and in deliverability — mailbox providers read dead recipients as a spam signal. Cutting them is what every deliverability consultant already charges to recommend.
Yes — Klaviyo's docs describe the manual flow: build the segment, run a sunset flow, bulk-suppress, then remember to lower your tier. Deadweight is that whole checklist, automated, plus a watchdog so the savings don't quietly evaporate at the next billing cycle.
The audit is free and tells you your exact number. If you want Deadweight to act on it and keep watch, it's $19/mo — flat, any list size. If your audit shows savings under $19/mo, we'll tell you not to buy.
