Terms of Service

0. Authentication & Access

Access to Mailburster is secured through Stack Auth-based authentication workflows, including passwordless and OAuth-based identity verification where enabled. You are responsible for maintaining the security of your authentication methods, devices, and linked identity providers. Any actions performed through an authenticated session are considered authorized by your account.

1. Acceptance of Terms

By accessing, registering for, or using Mailburster, you agree to these Terms of Service. These Terms apply to all use of the platform including campaign creation, CSV imports, AWS SES integrations, merge-tag personalization, analytics dashboards, exports, APIs, and related features. If you do not agree, you must discontinue use immediately.

2. Eligibility & Authority

• You must be at least 18 years old.
• You must have authority to bind your company, client, or organization.
• You may only send campaigns on behalf of identities you control or are authorized to use.
• You are responsible for ensuring compliance with local and international communication laws.

3. Account Security

• You are responsible for protecting your login credentials and connected AWS keys.
• Any activity performed through your account is deemed authorized by you.
• You must notify us immediately if you suspect unauthorized access.
• We may suspend access if suspicious activity, abuse, or credential compromise is detected.

4. Recipient Data & Consent

You retain ownership of all uploaded CSV recipient data, merge tags, and campaign content. You represent that all recipients were collected lawfully and that you have the required legal basis, consent, or legitimate interest to contact them. Mailburster may automatically remove invalid, duplicate, bounced, or complained addresses to protect deliverability.

5. AWS SES, SNS & Cloud Responsibility

Mailburster acts as a campaign workflow, orchestration, and analytics layer on top of your connected AWS infrastructure. All Amazon SES and Amazon SNS usage charges, including email sending, event notifications, bounce destinations, complaint webhooks, click/open tracking events, and any related AWS bandwidth or storage costs, are solely your responsibility and will be billed directly by AWS to your account. You are also fully responsible for SES quotas, sandbox restrictions, suppression behavior, DNS alignment, account reputation, and AWS enforcement actions. Mailburster is not liable for AWS throttling, suspensions, blacklisting, SNS delivery failures, or AWS-wide incidents.

6. Acceptable Use & Anti-Spam

• No unsolicited bulk email or spam.
• No purchased, rented, scraped, or third-party contact lists.
• No phishing, spoofing, impersonation, or deceptive subject lines.
• No malware links, harmful redirects, or fraudulent offers.
• All campaigns must include legally required opt-out mechanisms where applicable.

7. Tracking & Analytics

Mailburster tracks sends, deliveries, opens, clicks, bounces, complaints, unsubscribes, and suppressions on a best-effort basis. Metrics may be impacted by privacy proxies, image blocking, mailbox provider scanners, bot clicks, delayed event destinations, or AWS webhook latency. Analytics should be treated as directional operational data rather than guaranteed exact numbers.

8. Data Retention

Uploaded CSV files may be automatically deleted after a retention period. Aggregated analytics may remain available longer for reporting purposes. Raw logs may be archived for abuse detection, billing disputes, debugging, and compliance obligations. You are responsible for exporting reports you need before deleting campaigns or closing your account.

9. Billing & Subscription

Mailburster subscription fees cover access to the software platform, campaign workflow, dashboards, exports, and premium features depending on your plan. AWS SES sending costs are always billed separately by Amazon Web Services. Subscription fees are billed in advance and are non-refundable unless otherwise stated.

10. Suspension & Termination

We may suspend campaigns or accounts immediately if bounce or complaint thresholds exceed safe limits, if abuse patterns are detected, if payments fail, or if continued use creates operational or legal risk. Upon termination, campaign data may be deleted after a grace period, though limited logs may be retained for compliance and fraud prevention.

11. Disclaimer of Warranties

Mailburster is provided on an ‘as is’ and ‘as available’ basis without warranties of any kind. We do not guarantee uninterrupted uptime, inbox placement, event accuracy, delivery success, or compatibility with every mailbox provider behavior.

12. Limitation of Liability

To the fullest extent permitted by law, Mailburster is not liable for indirect losses, lost revenue, sender reputation damage, AWS charges, SES account actions, blacklisting, inaccurate analytics, downtime, or customer disputes. Our maximum liability is limited to the total fees paid by you in the 12 months preceding the claim.
