We may suspend or terminate accounts that violate these rules without notice.

3. Your content & contacts

You retain ownership of the campaigns, templates, and contacts you upload ("Your Content"). You grant us a limited license to host, process, and transmit Your Content solely to operate the Service. You represent that you have permission to email every recipient you upload.

4. Gmail & third-party services

The Service sends mail through Gmail accounts you connect via Google OAuth. Your use of Gmail is also governed by Google's terms. You are responsible for maintaining the health and reputation of your Gmail accounts and complying with Google's policies.

5. Subscriptions & billing

Paid plans are billed in advance on a recurring basis. You can cancel anytime; cancellation takes effect at the end of the current billing period. Fees are non-refundable except where required by law.

6. Free trial

If we offer a free trial, we may modify or end it at any time. After the trial, your account converts to a paid plan unless you cancel.

7. Service availability

We strive to keep the Service available but do not guarantee uninterrupted access. We may modify, suspend, or discontinue features at any time.

8. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT GUARANTEE DELIVERABILITY OR THAT YOUR GMAIL ACCOUNTS WILL NOT BE LIMITED OR SUSPENDED BY GOOGLE.
