Terms of Service
Effective and last updated: July 17, 2026
These Terms govern your use of terriblemail, an email API and programmatic inbox service operated by terrible llc. By creating an account or using the service, you agree to these Terms.
1. The service
terriblemail provides APIs, MCP tools, hosted account management, and related infrastructure for sending and receiving email. Features, limits, and availability may change as the service develops. We may use third-party infrastructure providers to deliver the service.
Email delivery is inherently dependent on recipient systems, network conditions, sender reputation, and third-party providers. We do not guarantee delivery, inbox placement, delivery time, or uninterrupted availability.
2. Eligibility and accounts
You must be at least 18 years old and legally able to enter into a contract. If you use terriblemail for an organization, you represent that you have authority to bind it. You must provide accurate account information, secure your password and API keys, and promptly notify help@terrible.llc of suspected unauthorized access.
You are responsible for every request made with your credentials and for the applications, agents, recipients, content, and workflows connected to your account.
3. Acceptable use
You must comply with our Acceptable Use and Anti-Spam Policy and all laws applicable to your messages and recipients. You may not use terriblemail for spam, phishing, impersonation, malware, harassment, unlawful content, deceptive practices, or attempts to damage our systems or shared sender reputation.
We may investigate suspected abuse and throttle, suspend, or terminate access when reasonably necessary to protect recipients, third parties, the service, or our providers.
4. Plans, quotas, and billing
Paid subscriptions renew monthly in United States dollars (USD) until canceled. Current pricing and quotas appear on the pricing page. Taxes may be added where required. Quotas are hard limits, not metered overages. Sending to multiple recipients consumes one delivery unit per recipient.
By purchasing a subscription, you authorize our payment processor to charge the payment method on file at the start of each billing period. Failed or reversed payments may result in downgrade, suspension, or termination.
5. Cancellation and refunds
You may cancel through the customer billing portal. Cancellation takes effect at the end of the current paid billing period, and paid access ordinarily remains available until then. Payments are non-refundable except where required by law. The Cancellation Policy and Refund and Dispute Policy are incorporated into these Terms.
6. Your content and data
You retain ownership of content you submit. You grant terrible llc a limited, worldwide license to process, transmit, store, copy, and disclose that content only as reasonably necessary to operate, secure, support, and comply with law for the service. You represent that you have all rights and permissions needed to provide the content and address messages to each recipient.
Our handling of personal information is described in the Privacy Policy.
7. Our intellectual property
The service, site, software, documentation, branding, and related materials are owned by terrible llc or its licensors. These Terms grant only a limited, revocable, non-transferable right to use the service during your account term. They do not transfer ownership of our intellectual property.
8. Suspension and termination
You may stop using the service at any time. We may suspend or terminate access for a material breach, abuse, security risk, legal requirement, nonpayment, excessive bounces or complaints, or conduct that threatens the service or third parties. When practical, we will provide notice and an opportunity to cure. Serious or urgent abuse may require immediate action.
Account termination does not erase payment obligations already incurred. Data is deleted or de-identified according to the Privacy Policy and applicable retention requirements.
9. Disclaimers
To the maximum extent permitted by law, the service is provided “as is” and “as available.” terrible llc disclaims implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty arising from course of dealing or usage. You are responsible for deciding whether the service is appropriate for your use and for maintaining your own records and recovery plans.
10. Limitation of liability
To the maximum extent permitted by law, terrible llc and its members, employees, contractors, and suppliers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, revenue, data, goodwill, or business interruption. Our aggregate liability arising from the service will not exceed the amount you paid terrible llc during the 12 months before the event giving rise to the claim. These limitations do not apply where prohibited by law.
11. Indemnification
You will defend and indemnify terrible llc and its personnel from third-party claims, damages, and reasonable costs arising from your content, recipients, applications, violation of these Terms or the Acceptable Use Policy, or violation of another person’s rights, except to the extent caused by terrible llc.
12. Changes
We may update these Terms. We will post the revised date and provide reasonable notice of material changes through the service or account email. Continued use after the effective date of a change constitutes acceptance. If you do not agree, you must stop using the service and cancel any subscription.
