Terms of Service

Last updated: October 17, 2026

By signing up for or using PingMail.Cloud ("PingMail", the "Service"), you ("Customer") agree to these Terms of Service. The Service is operated by StarkOne, LLC ("StarkOne", "we"), a United States limited liability company, 390 Northeast 191st Street, Miami, FL 33179, USA.

1. Account & eligibility

• You must be at least 18 years old or otherwise legally able to enter contracts.
• You're responsible for everything that happens under your account, including sub-users and API keys.
• Keep API keys, SMTP credentials, and dashboard passwords secret. Notify us immediately if you suspect compromise.

2. Acceptable Use Policy

The following are strictly prohibited and will result in immediate suspension:

• Spam. Sending unsolicited bulk mail. Every recipient must have opted in.
• Phishing, fraud, malware. Including pretending to be another brand, distributing executables, or running credential-harvesting campaigns.
• Illegal content. CSAM, terrorism content, copyright infringement, anything that violates applicable law.
• Harassment. Targeted abuse of individuals.
• Reputation laundering. Using our IPs to send mail you wouldn't put your own name on.
• Circumvention. Bypassing rate limits, quotas, or DKIM/SPF checks by any technical means.

3. Sender authentication

You must verify each sending domain (SPF + DKIM) before sending production traffic. We provide tools to make this one click via Cloudflare. Sends from unverified domains are rejected.

4. Plans, billing & quotas

• New accounts start with a 14-day free trial of the Pro plan. No payment details are required for the trial. If no paid plan is chosen by the end of the trial, the account moves to the Free plan automatically and nothing is charged.
• Free plan: 500 sends/month, single domain.
• Paid plans are billed monthly in advance through our payment processor, Stripe. Current prices are listed on the pricing page. Prices are in US dollars and do not include taxes that may apply.
• The seller of record is StarkOne, LLC. Charges appear on your card statement as STARKONE, LLC.
• Monthly quota resets on the 1st of each month UTC.
• Exceeding quota returns HTTP 402 on the API (SMTP answers 452) until you upgrade or the month resets.
• Plan changes take effect immediately and are prorated on the next invoice.
• You can cancel at any time from the Billing tab of the dashboard. The paid plan stays active until the end of the period already paid for; the account then moves to the Free plan.
• No refunds for unused portion of a paid month, unless required by law.
• We may change pricing with 30 days' notice; existing prepaid periods stay at the old price.

5. Service availability

We target 99.9% monthly uptime for the API and SMTP relay. If we miss it, paid customers can claim a prorated credit by emailing [email protected] within 30 days of the incident. Credits cap at one month of fees. The status page is at status.pingmail.cloud.

6. Suspension & termination

• We may suspend the account if (a) AUP is violated, or (b) a regulator or upstream provider requires it.
• If a payment fails, Stripe retries it for several days. If it still cannot be collected, the paid subscription ends and the account moves to the Free plan.
• You may terminate at any time from the dashboard; service continues until the end of the current paid period.
• On termination, mail data is retained per the Privacy Policy then deleted.

7. Customer data

You retain ownership of all email content and contact data you send through the Service. You grant us a limited license to process it solely for delivering, debugging, and operating the Service. We do not use your content for advertising or model training.

8. Warranties & disclaimers

The Service is provided "AS IS". To the maximum extent permitted by law, we disclaim all implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that mail will be delivered to any specific inbox — deliverability depends on receiver-side filters we don't control.

9. Limitation of liability

To the maximum extent permitted by law, our aggregate liability for any claim under these Terms is limited to the fees you paid us in the 12 months preceding the claim. We are not liable for indirect, incidental, consequential, or punitive damages (including lost profits, lost data, or business interruption).

10. Indemnification

You agree to indemnify and hold StarkOne harmless from any third-party claim arising from (a) your content, (b) your violation of these Terms, or (c) your violation of any law.

11. Governing law

These Terms are governed by the laws of the State of Israel. Disputes are subject to the exclusive jurisdiction of the courts of Tel Aviv-Jaffa.

12. Changes to these Terms

We may update these Terms; we'll email account holders 30 days before any material change. Continued use after the effective date constitutes acceptance.
