MailAdx delivers ads inside email newsletters. We believe in transparent, respectful advertising. Learn how our ads work and how to opt out permanently.

How MailAdx Ads Work

If you see an ad powered by MailAdx in a newsletter, here is exactly what happened — and what did not.

No Behavioural Tracking

MailAdx does not use cookies, browser fingerprinting, or cross-site tracking. Ads are contextual — shown based on the newsletter you subscribed to, not your browsing history.

Hash-Only Identity

Your email is never stored in plain text on our ad-serving infrastructure. We receive only a one-way SHA-256 hash — mathematically irreversible — used solely for frequency capping.

Publisher Control

Every newsletter publisher on MailAdx explicitly enables ads and controls floor pricing and accepted formats. You only see ads in newsletters you chose to subscribe to.

Permanent Opt-Out

Use the form below to remove your email from all MailAdx ad targeting permanently. We store your hashed email in a suppression list — no ad will ever be shown to you again.

Who placed this ad?

This ad was served by MailAdx on behalf of an advertiser whose campaign matched the newsletter you were reading. The publisher (newsletter owner) enabled MailAdx and accepted these ads into their newsletter. MailAdx is the ad-serving technology layer.

For more detail on how we select and serve ads, read our Privacy Policy.
