Cancellation Mailstrom: Simple Process
What is Mailstrom
Mailstrom is an email management service that helps users clean and organize large inboxes by grouping, filtering, and removing messages in bulk. It is offered by 410 Labs and provides tiered subscription plans with features such as inbox removal, filters, and multiple account support.
How to cancel Mailstrom
- Web (direct): Sign in at mailstrom.co/settings, go to your account or billing settings and select the cancel option. According to Mailstrom’s Terms of Service, cancellation via the website takes effect immediately.
- App Store / Google Play: Mailstrom’s official documentation provides no cancellation details for App Store or Google Play subscriptions. If you subscribed through Apple or Google, cancel and request refunds (if applicable) through your Apple ID or Google Play account using Apple/Google’s refund processes.
What happens when you cancel
When you cancel via the Mailstrom website, cancellation takes effect immediately. Your active subscription will stop renewing after cancellation. Access to paid features may end at the moment of cancellation (Mailstrom’s documentation states cancellation takes effect immediately), and you should save any data you need before cancelling. For subscriptions started through Apple or Google, service and access rules may follow platform-specific timing (for example, some platform subscriptions remain active until the end of the paid period).
Will I get a refund?
Mailstrom’s Terms of Service state that paid plans are prepaid and non-refundable; no refunds or credits are provided for partial months or years. There is no mention in Mailstrom’s published policies of a statutory 14-day "cooling-off" refund right. Canadian consumers should be aware that while Mailstrom disclaims refunds, provincial consumer protection rules may provide additional rights in certain circumstances. If you believe a statutory right applies, you may need to pursue it with your card issuer, a provincial consumer protection agency, or via a chargeback/dispute with your payment provider.

Mailstrom lists prices in USD and appears to bill in USD at checkout. The Canadian dollar equivalent will depend on current exchange rates and any currency conversion/processing charges your bank or card issuer applies. Users have reported actual annual charges in CAD higher than a straight USD-to-CAD conversion due to billing date rates and fees.
Your consumer rights in Canada
Mailstrom’s published terms do not reference a 14-day cooldown or similar statutory cancellation right for Canadian customers. Under Canadian consumer protection laws, some distance-selling and digital content rules can vary by province (for example, Quebec’s consumer protection regime differs from other provinces). Company refund policies that say "non-refundable" may not always override statutory consumer protections. If you think a provincial right applies, verify the applicable provincial statute or contact your provincial consumer protection office. For payment disputes, Canadians often pursue a credit-card chargeback or contact their bank; the platform-specific stores (Apple/Google) also have their own refund and dispute processes.
Customer experiences
User feedback is mixed. Some reviews praise Mailstrom’s ability to manage cluttered inboxes and describe it as highly effective for bulk cleanup. Conversely, some users report negative experiences around billing - for example, instances where a user said they were still charged after cancelling and had a refund request refused. Other criticism focuses on limitations of unsubscribe automation (one-click unsubscribe works only when an unsubscribe address is present, and some unsubscribe flows require manual steps). These experiences suggest that cancellations via the website generally work, but billing and refund outcomes can vary and may require follow-up with the company or your payment provider.
Documentation checklist
- Account email and username
- Subscription receipts or order confirmations (showing transaction date and amount)
- Billing statement entry (credit card or bank) showing the charge
- Screenshots of your account settings showing the subscription and the cancellation confirmation (if available)
- Any communications with Mailstrom support (emails or support ticket IDs)
Common mistakes
Users commonly make preventable errors such as cancelling only within the app while the subscription was purchased through Apple or Google - in that case the platform subscription must be cancelled through the respective App Store/Google Play account to stop future charges. Another frequent mistake is not saving a cancellation confirmation or receipt; without documentation, proving the cancellation date can be harder if a charge appears after cancellation. Finally, not checking the billed currency or exchange rate can cause surprise at the CAD amount billed versus the USD price shown at checkout.
Comparative recap
| Method | Refund | Difficulty |
|---|---|---|
| Web (direct via mailstrom.co/settings) | None per Mailstrom policy (prepaid, non-refundable) | Low - cancellation via settings; takes effect immediately |
| App Store / Google Play subscription | Platform-specific - refunds processed by Apple/Google, not Mailstrom | Medium - cancellation via App Store/Google Play account; refund requests via platform support |
| Payment dispute / chargeback through bank or card issuer | Possible - depends on issuer’s investigation and applicable consumer protections | High - requires documentation and may take time |
After cancelling
After you cancel, keep copies of cancellation confirmations, receipts, and any related emails. If you need to follow up, start with Mailstrom’s settings page and Terms of Service: mailstrom.co/settings and Mailstrom Terms of Service. For App Store or Google Play subscriptions, use Apple’s refund and subscription help (Request a refund from Apple) or Google Play’s subscription and refund help (Google Play refunds). If a charge appears after cancellation and Mailstrom does not provide a refund, consider contacting your card issuer to dispute the charge and provide your cancellation documentation.
