To cancel a Happy Mammoth subscription, log in to the subscription portal at store.happymammoth.com/tools/recurring/login, verify your email, and cancel the active subscription before 11:00 PM the night before your next billing date. One catch to know before you click: every Happy Mammoth subscription carries a three-order minimum, and leaving before your third shipment triggers an early cancellation fee.
The Three-Order Minimum and What Leaving Early Costs
Every subscription product on the Happy Mammoth site is sold with a three-order minimum term. The commitment is disclosed on each product page at checkout, and the company treats it as the subscriber’s responsibility to read before signing up.1Happy Mammoth. Support
Cancel before your third order ships and you’ll be charged an early cancellation fee. The fee is either $49 or the price difference between the one-time purchase price and the discounted subscription price for the orders you’ve already received, whichever is lower.1Happy Mammoth. Support In practice, that means the subscription discount you’ve enjoyed so far gets clawed back, up to $49.
If you’re past your third shipment, no fee applies and cancellation is simply a matter of hitting the deadline.
Cancellation Deadlines Depend on How You Cancel
Using the online portal, your cancellation has to be submitted by 11:00 PM the night before your next billing date. If you cancel by email, the deadline moves earlier: at least two full days before your subscription’s auto-renewal date.2Happy Mammoth. Terms of Service
Miss either window and the next order processes and ships. Once a Happy Mammoth order has shipped, refunds are extremely difficult to obtain, so if you’re close to a renewal date, don’t wait. Canceling early carries no penalty, and your access stays active until the renewal that would have come next.
You can see your next billing date by logging into the portal and checking the upcoming shipment schedule.
Canceling Through the Online Portal
The portal is the fastest route and the only one with the later same-night deadline. Go to store.happymammoth.com/tools/recurring/login and enter the email address tied to your subscription. The system emails a verification code, which replaces a password.
Once you’re in:
- Find your active subscription on the dashboard.
- Select the option to cancel it.
- Answer the exit survey if one appears. Giving a reason is standard and does not stop the cancellation.
- Click through to the final confirmation screen.
- Screenshot the confirmation before you navigate away.
You should also receive a confirmation email at the account address. Keep it.
Canceling by Email or Live Chat
If the portal won’t cooperate, email support@happymammoth.co or use the live chat on the Happy Mammoth contact page.3Happy Mammoth. Contact Us The company does not publish a phone number for customer service.
An email cancellation should include your full name, the email address on the account, and a clear statement that you want the subscription canceled. Keep it short. The two-day-before-renewal deadline is firm for this method,2Happy Mammoth. Terms of Service so don’t use email if you’re already close to your billing date. The upside of email is a timestamped written record, which helps if a charge later needs to be disputed.
Live chat can be quicker when agents are online. Save or screenshot the transcript before closing the window.
Skip or Pause Instead of Canceling
If you’re still inside the three-order window and want to avoid the fee, the portal lets you skip a shipment or stretch the interval between deliveries.4Happy Mammoth. Support The subscription stays active, no early-exit fee is triggered, and you buy yourself time until you’ve received three orders and can cancel cleanly.
Log into the same subscription portal and look for the option to adjust the next shipment date or change delivery frequency.
Canceling Does Not Refund a Shipped Order
Happy Mammoth treats its supplements and bone broth as perishable goods and does not accept physical returns once a product has left the warehouse. If your next order ships before your cancellation lands, the default position is no refund and no exchange.5Happy Mammoth. Refund Policy
The company does offer a 60-Day Money-Back Guarantee, but it only applies to single-jar or one-month purchases, requires that you’ve taken the product as directed for the full period, and permanently blocks you from buying that product again once you claim it. For gut products such as Prebiotic Collagen Protein, you also have to show you consumed at least nine servings while avoiding alcohol and junk food during the trial.5Happy Mammoth. Refund Policy It is not a general refund route for a shipment you canceled too late.
Stopping the Charge at Your Bank
If a cancellation won’t go through, or charges continue after you’ve canceled, federal rules on preauthorized electronic transfers let you stop a recurring charge by notifying your bank or card issuer at least three business days before the next scheduled transfer. You can make the request by phone or in writing. If you call, the bank may require written confirmation within 14 days or the stop-payment order expires.6eCFR. 12 CFR 1005.10 – Preauthorized Transfers
Treat this as a last resort. Blocking the payment at the bank does not cancel your agreement with Happy Mammoth, so still complete the cancellation through the portal or support to avoid a claim that you owe under the subscription terms.
Confirming the Cancellation Took
After you cancel, you should receive a confirmation email, and the subscription status in your account dashboard should flip from active to canceled. Save both.
Watch your bank or card statements through the next billing cycle. If a charge posts after your confirmed cancellation, your email confirmation and screenshots are what you’ll need to dispute it with your bank. The FTC’s click-to-cancel rule also requires subscription sellers to stop charges once a consumer cancels, which gives you a complaint route if post-cancellation charges keep coming.7Federal Trade Commission.
