Terms of Service

Acceptance of Terms

By accessing or using Postflare ("the Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms, you may not use the Service.

These Terms apply to all users, including individuals and organizations that create accounts, access the API, or otherwise use the Service.

Service Description

Postflare is an email sending platform built on Cloudflare infrastructure. The Service provides:

• A REST API and dashboard for sending transactional emails
• Broadcasts and tools for managing contacts, segments, and topics
• Domain verification and DNS management for email authentication
• Email delivery tracking and analytics
• Webhook notifications for email events

The Service may be used to send broadcasts, including marketing emails. You must follow applicable unsubscribe requirements and anti-spam laws, and send only to recipients who have given the required consent.

Account Registration

To use the Service, you must create an account. You agree to:

• Provide accurate and complete registration information
• Maintain the security of your account credentials and API keys
• Notify us immediately of any unauthorized access to your account
• Accept responsibility for all activity that occurs under your account

You must be at least 18 years old or the age of legal majority in your jurisdiction to create an account.

Acceptable Use Policy

You agree not to use the Service to:

• Send spam: Unsolicited bulk emails, including commercial messages sent without recipient consent
• Send phishing emails: Messages designed to deceive recipients into revealing personal information
• Distribute malware: Emails containing viruses, malicious code, or harmful attachments
• Send unauthorized bulk email: High-volume emails without proper recipient opt-in
• Harass or threaten: Messages that are abusive, threatening, or intended to intimidate
• Violate laws: Any activity that violates applicable local, national, or international law

Delivery Quality Requirements

Deliverability is shared across the platform, so we require every sender to maintain the following rates:

• Bounce rate: below 4%
• Complaint (spam report) rate: below 0.08%

The Service monitors bounce and complaint rates. When sending crosses the configured bounce or complaint thresholds, the Service automatically pauses sending and alerts our operations team. A person reviews the account and may resume sending or suspend the organization. Sustained sending above these rates, or sending that violates this Acceptable Use Policy, may also result in the measures described below.

Anti-Abuse Measures

We actively monitor for abuse. Accounts found in violation of this Acceptable Use Policy may be:

• Rate-limited or throttled
• Suspended with notice
• Terminated immediately for severe violations

Compliance Requirements

You are responsible for ensuring your use of the Service complies with all applicable laws and regulations, including but not limited to:

• CAN-SPAM Act (United States)
• GDPR (European Union)
• CASL (Canada)
• Any other applicable anti-spam or data protection legislation

Service Tiers and Limits

How Emails Are Counted

Wherever these Terms, the dashboard, or our documentation state a number of emails, one email means one recipient address on one message. A single API request naming multiple recipients in to, cc or bcc counts as one email per address. A request naming 100 addresses therefore consumes 100 emails from your monthly allocation, not one.

Emails you receive through the Service count towards the same monthly allocation as emails you send.

An email counts towards your allocation when we perform the send on your behalf — including when the recipient address is refused because it is on your suppression list, and including when the message is subsequently bounced or reported as spam. An email does not count towards your allocation if you cancel it before it is sent, if it is scheduled and has not yet been sent, or if the Service fails to compose or dispatch it.

A full description, including how broadcasts sent to a segment are counted, is published in our quota and sending limits documentation.

Plans

The Service is offered in plans. The monthly email allocation, the number of sending domains, and the other limits and features of each plan are as described in our pricing, shown on the Billing page of your organization's settings in the dashboard. Daily sending limits may also apply and depend on your plan, account age, and domain verification status. Sending requests that exceed a daily limit are rejected.

Rate Limits

• Sending requests above an applicable daily limit are rejected with a 429 Too Many Requests response
• Email sending beyond your monthly allocation will be rejected until the next billing cycle
• We reserve the right to adjust limits to prevent abuse or maintain service quality

API Usage

• API Key security: You are solely responsible for safeguarding your API keys. Treat them as sensitive credentials and never expose them in client-side code or public repositories.
• Rate limiting: Use the API responsibly. Implement exponential backoff for retries and respect rate limit headers.
• Versioning: We may provide notice before deprecating API versions or making breaking changes.

Intellectual Property

The Postflare name, logo, and branding are the intellectual property of Postflare. You may not use our branding without prior written consent.

Content you send through the Service remains your property. We do not claim ownership of your email content, templates, or data.

Open-source components of Postflare are licensed separately under their respective licenses.

Limitation of Liability

The Service is provided on an "AS IS" and "AS AVAILABLE" basis. We do not guarantee:

• 100% uptime or availability
• Delivery of every email to the recipient's inbox
• That the Service will be error-free or uninterrupted

To the maximum extent permitted by law:

• We are not liable for indirect, incidental, special, or consequential damages arising from your use of the Service
• Our total liability is limited to the amount you paid for the Service in the 12 months preceding the claim
• We are not responsible for damages resulting from email delivery failures, including lost revenue, missed communications, or business disruption

Termination

By You

You may terminate your account at any time through the dashboard settings or by contacting us. Upon termination:

• Your API keys will be immediately revoked
• Any outstanding payment obligations remain due

By Us

We may suspend or terminate your account if:

• You violate these Terms or the Acceptable Use Policy
• Account inactivity may result in termination
• We are required to do so by law

For non-urgent violations, we will provide 7 days' notice before termination. Severe violations (e.g., sending malware, phishing) may result in immediate termination without notice.

Governing Law

These Terms are governed by and construed in accordance with applicable law. Any disputes arising from these Terms or your use of the Service will be resolved through good-faith negotiation first, and if unresolved, through binding arbitration or the courts of competent jurisdiction.

Changes to Terms

We may modify these Terms from time to time. When we make material changes:

• We will update the "Last updated" date and version number at the top of this page
• We may notify you by email before material changes take effect
• Your continued use of the Service after the effective date constitutes acceptance of the modified Terms

If you do not agree to the modified Terms, you must stop using the Service and close your account before the effective date.
