1. Record the current billing state
Save the current plan, active-profile count, next renewal date and recent invoices. Take dated screenshots of any profile-count or auto-downgrade mismatch. The Klaviyo ledger contains 31 pricing-classified records, so a written starting point is useful if the final charge is disputed.
2. Export what cannot be rebuilt from memory
- Consented contacts and consent evidence
- Suppression and unsubscribe lists
- Flow logic, triggers, timing and message copy
- Reusable email templates and brand assets
- Recent reports needed for comparison
- Integration and webhook notes
3. Suppress before you cancel
Clean duplicates, bots, hard bounces and addresses you cannot lawfully email. Apply suppressions while the account is paid, accessible and still connected. Do not assume an API success response means every profile changed.
The trap: the supplied instattoo case describes a suppress-requires-payment loop. The API reported that the job completed but skipped 100 out of 100 profiles. Payment was needed to suppress, while suppression was needed to reduce the bill.
4. Prepare the replacement before traffic moves
Authenticate SPF, DKIM and DMARC, import suppressions before active contacts, recreate essential flows, and send internal tests. A small warmup is safer than moving the entire volume on day one.
5. Cancel, then preserve the confirmation
Use the cancellation path inside the account, save the confirmation, and keep the final invoice. Check the next billing date rather than assuming the absence of campaigns means the subscription ended.
