You may not create multiple free accounts for the purpose of circumventing service limits, and doing so may result in the termination of all associated accounts without notice.

5. Subscription Plans and Fees

The Service offers both free and paid subscription plans. Each plan provides specific features, storage allocations, and account limits as described on our pricing page at the time of purchase.

• Free Plan: Subject to limitations on storage, mailboxes, and features. The Free Plan may be modified, reduced, or discontinued at any time at the Company's sole discretion.

• Addon Products: Additional features or services (such as webmail rebranding, reseller tools, or premium applications) may be purchased separately and are subject to their own pricing and terms.

The Company reserves the right to change pricing for any plan or addon at any time. Price changes for existing paid subscriptions will take effect at the start of the next billing cycle following notice to you.

6. Payment Terms and Billing

All paid subscriptions are processed through our third-party payment processor, Stripe. By subscribing to a paid plan, you agree to Stripe's terms and authorize us to charge your designated payment method on a recurring basis.

• Automatic Renewal: Paid subscriptions renew automatically at the end of each billing period unless cancelled before the renewal date.
• Failed Payments: If a payment fails, we may retry the charge, suspend your access to paid features, or downgrade your account to the Free Plan. We are not obligated to provide notice before taking such action.
• Taxes: All fees are exclusive of applicable taxes, levies, or duties. You are responsible for paying all such taxes associated with your use of the Service.
• Currency: All prices are listed in United States Dollars (USD) unless otherwise stated.

7. No Refund Policy

By subscribing to a paid plan, you acknowledge and agree that no refunds will be issued under any circumstances, including but not limited to dissatisfaction with the Service, accidental purchases, failure to cancel before a renewal date, or account termination due to policy violations.

If you wish to cancel your subscription, you may do so at any time through your account dashboard. Cancellation will take effect at the end of your current billing period, and you will retain access to paid features until that date.

8. Free Plan

The Free Plan is provided as a courtesy and may be modified, limited, or discontinued at any time without prior notice. The Company makes no guarantees regarding the availability, features, storage limits, or performance of the Free Plan.

Free Plan accounts that remain inactive (no login or email activity) for a period of ninety (90) consecutive days may be automatically suspended or deleted, including all associated data, without notice.

The Company reserves the right to impose additional restrictions on Free Plan accounts, including but not limited to rate limiting, reduced storage, or limited sending capabilities, at any time.

The Company shall not be liable for any failure to perform its obligations under these Terms where such failure results from events beyond our reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, riots, government actions, power failures, internet or telecommunications failures, or attacks on our infrastructure (including DDoS attacks).

25. Severability

If any provision of these Terms is held to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such provision shall be modified to the minimum extent necessary to make it valid and enforceable, or if modification is not possible, shall be severed from these Terms. The invalidity or unenforceability of any provision shall not affect the validity or enforceability of the remaining provisions, which shall continue in full force and effect.
