Cancellation Klaviyo: Easy Method
What is Klaviyo
Klaviyo is a marketing automation and customer-data platform focused on email, SMS, and related marketing tools for ecommerce and online businesses. It provides segmentation, multichannel campaigns, automated flows, and analytics designed to integrate with platforms such as Shopify and other commerce stacks.
Organizations use Klaviyo to build personalized campaigns, manage subscriber lists, and automate lifecycle messaging; plans and billing are managed from within each Klaviyo account.
How to cancel Klaviyo
- Log in to your Klaviyo account and go to the Billing section; only account Owners or Admins can cancel or downgrade, and only Owners can close an account.
- Choose whether to cancel immediately (service and integrations may be disabled at once) or to cancel at the end of the current billing cycle (recommended to avoid losing access before you finish work).
- Confirm the cancellation following the on‑screen prompts; save screenshots or copies of the confirmation and any billing information for your records.
- If you cannot cancel through the Billing page or you need assistance, contact Klaviyo Support via your account or the Help Center linked above; for formal notices you may also consider sending registered mail to the company headquarters (address below).
What happens when you cancel
Cancelling a Klaviyo plan or account can take effect immediately or at the end of your current billing cycle depending on the option you choose in the Billing section. If you cancel immediately, integrations are disabled, scheduled campaigns will not be sent, and flows typically move to draft or stop running. If you elect to cancel at the end of the billing cycle, you generally retain access until that cycle ends.
Account closures and downgrades are controlled by account roles - Owners and Admins - and certain actions (like fully closing an account) can only be performed by the Owner. Keep exports of important lists, templates, and reports before cancellation if you may need the data later.
Will I get a refund?
Klaviyo’s documented policy states that refunds for the unused portion of a billing cycle are not issued after cancellation; users are advised to cancel toward the end of the billing cycle to avoid paying for time they will not use. Sales tax refunds may be possible for U.S. customers in specific circumstances (for example, if a tax exemption is approved) and are handled via support, but full-service refunds for unused time are generally not offered.
There is no publicly documented 14‑day cooling‑off or automatic refund right in Klaviyo’s Help Center materials; if you believe a statutory consumer right in Canada applies to your situation, you should check provincial consumer protection rules and, if applicable, raise the issue with Klaviyo support or your provincial regulator.
Klaviyo plans and pricing
| Plan / Feature | Price (CAD) | Billing model |
|---|---|---|
| Varies | Monthly or annual tiers based on contact count | |
| SMS / Conversations | Varies | Pay‑as‑you‑go credits and volume tiers for messages |
| Reviews (add‑on) | Varies | Paid add‑on or integrated pricing depending on selected package |
| Account / Free tier | Varies | Free tier available with limits; paid plans scale with usage |
Your consumer rights in Canada
Klaviyo’s internal policies state no refunds for unused service time, but these policies do not automatically override statutory consumer protections that may exist in Canada. Certain provinces (for example, Quebec and Ontario) have consumer protection rules that can apply to digital subscriptions and online services; those provincial rules may give consumers the right to cancel or to receive remedies in some circumstances.
If you believe a provincial consumer protection rule applies (for example, a statutory cancellation window or an unfair‑practice remedy), review the relevant provincial statutes or contact your provincial consumer protection office. If necessary, raise the statutory right when you contact Klaviyo support and keep documentation of your timelines and communications.
Customer experiences
Public reviews for Klaviyo in Canada are mixed. Many users on platforms such as Capterra and GetApp praise Klaviyo’s ease of use, powerful segmentation, analytics, and strong integrations with ecommerce platforms like Shopify. These strengths make it a popular choice for merchants who need advanced automation and personalization.
At the same time, negative feedback reported on Trustpilot, Shopify app reviews, and online forums includes complaints about customer service responsiveness, billing issues, unexpected charges, difficulties obtaining refunds, and occasional platform glitches. Several posts mention challenges contacting support or delays in receiving live assistance. Weighing these experiences, prospective cancellers should document billing dates, confirmations, and communications when interacting with Klaviyo.
Documentation checklist
- Account Owner/Admin name and email; screenshots showing your role.
- Billing cycle date, recent invoices, and payment receipts (screenshots or PDFs).
- Confirmation screenshot or email received at cancellation.
- Exports of lists, templates, and any data you need to retain.
- Support ticket numbers, chat transcripts, or email correspondence if you contact Klaviyo.
Common mistakes
Users commonly attempt to cancel from an account that lacks Owner or Admin permissions; this prevents cancellation actions and can cause delays. Another frequent mistake is cancelling immediately without exporting data or stopping scheduled campaigns - immediate cancellation may disable integrations and stop sends right away. Finally, some customers assume they will receive a prorated refund for unused service time; Klaviyo’s policy is that refunds are not provided for the remainder of a billing cycle, so plan your cancellation timing accordingly.
Comparative recap
| Method | Refund | Difficulty |
|---|---|---|
| Cancel via Billing page (in‑account): choose immediate or end‑of‑cycle | No refund for unused time (policy). Tax refunds uncommon and handled case‑by‑case. | Easy |
| Contact Klaviyo Support (in‑account) | Possible tax/exemption handling (mostly U.S. cases); service refunds generally not provided. | Medium (response times vary) |
| Owner closes account (full closure) | No prorated refunds per published policy; exceptions handled via support only. | Medium |
| Formal registered mail to headquarters | Does not guarantee a refund; useful for proof of notice or escalation. | Harder (slow; requires physical mailing) |
After cancelling
After you cancel, keep copies of the cancellation confirmation and any relevant invoices. If you need help or want to dispute a charge, open a support ticket from your Klaviyo account and reference the Billing article: Klaviyo Billing and Cancellations. For tax or billing disputes, raise the issue with Klaviyo Support; note that tax‑related refunds are typically handled case‑by‑case and support responses can take several business days.
If you believe a provincial consumer protection law provides additional rights (for example, a cancellation window), gather your documentation and consider contacting your provincial consumer protection office or a legal advisor before and after contacting Klaviyo.
