Terms of Service

If you do not agree to these Terms, do not use the Service. We may require you to accept updated Terms to continue using the Service, as described in “Changes to these terms” below.

Unitpost provides email infrastructure for developers: a sending API and SMTP, a dashboard, template tooling, deliverability analytics, event logs, and webhooks for transactional and marketing email. We may add, change, or remove features over time.

• You must be at least 18 years old and able to form a binding contract to use the Service.
• You are responsible for the activity under your account and for keeping your credentials, API keys, and sign-in access secure.
• You must provide accurate account information and keep it up to date. Notify us promptly of any unauthorized use.

You agree not to use the Service to send, store, or facilitate any content or activity that is unlawful, harmful, or abusive. In particular, you must not:

• Send unsolicited bulk or commercial email (spam), or email to recipients who have not consented or with whom you lack a valid relationship.
• Harvest, purchase, or use email lists you do not have permission to contact.
• Send phishing, malware, fraudulent, deceptive, or misleading content, or forge headers or sender identity.
• Distribute content that is illegal, infringing, defamatory, harassing, hateful, or sexually exploitative, or that violates the privacy or rights of others.
• Attempt to bypass sending limits, suppression lists, rate limits, or other technical or security controls.
• Reverse engineer, disrupt, overload, or gain unauthorized access to the Service or its infrastructure.

We may refuse, throttle, or remove content and restrict sending that we reasonably believe violates these rules, in order to protect deliverability and the platform for all customers.

• You are solely responsible for the content you send and for obtaining any required consent from your recipients.
• You must comply with all applicable email and anti-spam laws, including the CAN-SPAM Act, GDPR/ePrivacy, CASL, and similar laws.
• Marketing messages must include a functioning unsubscribe mechanism and honor opt-outs promptly. You must not send to addresses on your suppression list.
• You must properly authenticate your sending domains (SPF, DKIM, DMARC) as required to send through the Service.

You retain all rights to the data you submit, including recipient lists and message content (“Customer Data”). You grant us the rights necessary to process Customer Data to provide and improve the Service. As described in our Privacy Policy, we act as a processor for the personal data in the emails you send and process it only on your instructions. You are responsible for the lawfulness of the Customer Data and your instructions.

API keys authenticate requests to the Service and must be kept confidential; you are responsible for activity performed with your keys. We may apply rate limits, sending caps, and other technical limits, and may adjust them to protect the Service. Automated or programmatic use must stay within these limits.

• Paid plans are billed according to the pricing shown at our pricing page. Pricing is volume-based — you pay for the email you send.
• Fees are charged in advance for subscriptions and/or based on usage, through our payment processor. You authorize us to charge your payment method for all applicable fees.
• Except where required by law, fees are non-refundable. You are responsible for applicable taxes.
• We may change pricing on a prospective basis with reasonable notice. Continued use after a change means you accept it.
• If a payment fails or is overdue, we may suspend or limit the Service until amounts are paid.

The Service, including its software, design, and content (excluding Customer Data), is owned by Work Reactor Inc. and its licensors and is protected by intellectual-property laws. We grant you a limited, non-exclusive, non-transferable right to use the Service in accordance with these Terms. You may not copy, modify, or create derivative works of the Service except as expressly permitted. Any feedback you provide may be used by us without obligation to you.

The Service integrates with third-party providers (for example, payment, hosting, and delivery infrastructure). Your use of those services may be subject to their terms, and we are not responsible for third-party services. Links or integrations do not imply endorsement.

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you violate these Terms, if your use poses a security, legal, or deliverability risk, if required by law, or for non-payment. Where practical and lawful, we will give notice. Upon termination, your right to use the Service ends; sections that by their nature should survive (such as fees owed, IP, disclaimers, liability, and indemnity) will survive.

Please read this section carefully.

The Service is provided “as is” and “as available” without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that every email will be delivered, as deliverability depends on factors outside our control (including recipient mailbox providers and your sending practices).

To the maximum extent permitted by law, Work Reactor Inc. and its affiliates will not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill. Our total liability arising out of or relating to the Service and these Terms will not exceed the greater of the amounts you paid us for the Service in the twelve (12) months before the event giving rise to the claim, or USD $100. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.

You will indemnify and hold harmless Work Reactor Inc. and its affiliates from and against any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your Customer Data, your use of the Service, your content, or your violation of these Terms or applicable law.

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules. You agree to the exclusive jurisdiction of the state and federal courts located in Delawarefor any dispute not subject to another agreed dispute-resolution process. Nothing here limits either party’s ability to seek injunctive relief.

We may update these Terms from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, notify you. Your continued use of the Service after an update means you accept the revised Terms.
