Mainline Media Group ("MMG," "we," "us") is committed to protecting the privacy of our publishers, their subscribers, and visitors to our properties.
This page will be updated with our full privacy policy. In the meantime, this summary describes how we handle data, and you can always reach us at contact@mainline.media.
What we do. MMG operates as a newsletter subscriber scaling and monetization partner. We capture brand-aware visitors on publisher sites through pixel-based identity resolution, validate and deduplicate contacts, and warm them into existing publisher newsletters. We share ad revenue 50/50 with publishers.
What we collect. On participating publisher sites, our pixel may collect device and browser information, page engagement signals, and privacy-safe identifiers used to match a visitor to an email address. We validate and suppression-check every contact before any email is sent.
Your choices. Every email sent through our network includes a working unsubscribe link, honored promptly as required by the CAN-SPAM Act. To opt out of MMG-operated data collection entirely, or to request deletion of your information, email contact@mainline.media with the address you'd like removed.
For data deletion requests, privacy inquiries, or any questions about your information, reach us at contact@mainline.media. We respond within one business day.
