Anti-spam & acceptable use policy

Last updated: September 25, 2026

PingPing only works if recipients trust the email they get from it. Every customer must follow this policy. It is part of our terms of service.

1. Only email people you have the right to email

• Send only to recipients who have agreed to hear from you (for example by subscribing, opting in on a form, or asking to be kept informed) or with whom you have an existing business relationship, such as current or recent customers and people who asked you for information or a quote.
• Purchased, rented, borrowed, scraped or harvested lists are prohibited, as are lists "shared" by another company and addresses collected for a different purpose.
• Be ready to show how and when each contact agreed to hear from you or became a customer. We may ask.
• No sending to role or distribution lists you don't control, or to addresses you know have opted out.

2. Every email must

• Clearly identify your company as the sender, with accurate "From" and "Reply-to" details.
• Use a subject line that honestly reflects the content.
• Include your valid physical postal address.
• Include a working unsubscribe link. PingPing adds one automatically and supports one-click unsubscribe in email clients.

3. Honor opt-outs

Unsubscribes are applied automatically and immediately within PingPing. You may not re-add, re-import or email unsubscribed, bounced or complaining addresses, and you must honor opt-out requests you receive outside PingPing within 10 business days.

4. Prohibited content

• Anything illegal, deceptive or misleading, including false medical or scientific claims.
• Phishing, malware, or links that disguise their destination.
• Content for consumers rather than businesses, or unrelated to the life sciences.
• Harassment, hate or adult content.

5. Monitoring and enforcement

We monitor bounce and complaint rates and may review content and lists. We may pause a send, suspend sending, or close an account, with or without notice, when:

• complaint or bounce rates are high (as a guide, complaints above 0.1% or hard bounces above 5% of a send),
• we receive credible reports of spam or abuse, or
• a send puts recipients, our sending reputation, or other customers at risk.

6. The law

You are responsible for complying with the U.S. CAN-SPAM Act and any other laws that apply to your emails and recipients, including laws of other countries where your recipients are located.

7. Report abuse

If you received unwanted email sent through PingPing, use the unsubscribe link in the email and let us know at abuse@pingpingbio.com or through our contact form (topic "Report abuse / spam"). We investigate every report. Mail delivery problems: postmaster@pingpingbio.com.
