Terms of Service

Last updated: April 29, 2026

By installing or using MailPing ("the extension"), you agree to these terms. They are intentionally short and plain-language.

1. What MailPing is

MailPing is a Chrome extension that lets you see when emails you send through Gmail are opened, by injecting a 1×1 tracking pixel into outgoing messages. It is operated by Peak Productivity (the "we" / "us" in these terms).

2. Free and Pro plans

• Free , 10 tracked email sends per day, forever. There is no trial flip, no countdown, and no automatic conversion to a paid plan.
• Pro , Paid subscription that unlocks unlimited tracked sends, link click tracking, reply reminders, per-recipient open detection, CSV export, and use on up to 3 Gmail accounts on the same license.
• Team , 5-seat plan with centralised billing.

3. Acceptable use

You agree not to use MailPing to:

• Send spam or unsolicited bulk email in violation of CAN-SPAM, GDPR, or other applicable anti-spam laws.
• Track recipients in jurisdictions that require explicit opt-in for tracking pixels without obtaining that opt-in (e.g. some EU member states under ePrivacy guidance).
• Reverse-engineer, resell, sublicense, or wrap the extension in a competing product.
• Probe, scan, or DDoS our backend.

4. Refunds

Pro and Team subscriptions are billed monthly or yearly. Cancel any time and the cancellation takes effect at the end of your current billing period. We do not pro-rate refunds, but if you bought Pro within the last 14 days and have a genuine concern, email support@peakproductivity.online and we will refund without argument.

5. Service availability

We aim for 99.5% uptime but do not guarantee it. If our backend is unreachable, the local popup will still show your tracked-email history; new opens will be queued and counted once the backend is back.

6. Liability

MailPing is provided "as is" without warranty. We are not liable for any damages arising from missed opens, missed replies, deliverability issues caused by the tracking pixel, or any indirect/consequential damages. Aggregate liability is capped at the amount you paid us in the previous 12 months (which is $0 if you are on the Free plan).

7. Termination

You can stop using MailPing at any time by uninstalling the extension. We may suspend or terminate accounts that violate Section 3 (Acceptable use), with or without notice.

8. Changes to these terms

We may update these terms occasionally. Material changes will be announced via the extension popup at least 14 days before they take effect. Continued use after that constitutes acceptance.

9. Governing law

These terms are governed by the laws of Switzerland. Any dispute that cannot be resolved by discussion will be settled in the courts of Zürich.
