Terms and refunds

Last updated November 13, 2026.

The service

TierBrake prepares a dry-run list of Klaviyo profiles that are cold or likely bots, and after you approve it, suppresses them through Klaviyo's API before your renewal. We never suppress a profile with an order in the last 365 days. Klaviyo decides your plan and price; we don't control Klaviyo's billing.

Billing and cancelling

Plans are billed monthly in US dollars through Stripe. Cancel any time by emailing support@tierbrake.com; you won't be charged again after the current month.

First-renewal guarantee

If your first renewal with us doesn't land on a lower Klaviyo tier, we refund Month 1. Applies when the 3-step Klaviyo billing checklist is done before that renewal. Email us within 14 days of that renewal with a screenshot of your Klaviyo plan before and after, and we refund your first month's TierBrake payment.

Your responsibilities

You confirm you're allowed to give us access to the Klaviyo account, and you review each dry-run preview before approving it. Suppressed profiles can be unsuppressed in Klaviyo, subject to Klaviyo's rule that a profile unsuppressed after a manual suppression can't be manually suppressed again for 90 days.

Limits

TierBrake is provided as is. To the extent the law allows, our total liability is limited to what you paid us in the three months before a claim. TierBrake isn't affiliated with or endorsed by Klaviyo.
