Email intelligence firm OMC says 19% of “conversational” email, sent by people like friends, spouses, and business partners, is subject to email open tracking
“I JUST CAME across this email," began the message, a long overdue reply. But I knew the sender was lying.

Context & Ripple Effects
Open tracking has been visible to Gmail power users since at least 2015, when Wired covered Ugly Mail, a Chrome extension that flags which messages carry a tracking pixel. What OMC adds is scale: the practice is no longer a newsletter phenomenon but reaches roughly one in five person-to-person emails between friends, spouses, and business partners.
That finding reframes a recurring thread in this coverage — from Superhuman's read-receipt spying to Yahoo's Oath pitching advertisers on analysis of its mail inboxes — as one market: recipient behavior sold back to senders without the recipient's knowledge.
First-order effects
- Senders of ordinary conversational email gain silent visibility into when and where recipients open messages, while recipients like @Outlook iOS users have no built-in way to block remote image loading that fires the pixel.
Second-order effects
- Inbox providers are pushed into a defensive product race — Apple's later Mail Privacy Protection answers exactly this exposure by proxying or blocking remote images, at a cost to publishers who relied on open rates.
Third-order effects
- If pixel blocking spreads, measurement migrates from third-party trackers embedded in messages to platform-level access controlled by the mailbox owner — the same consolidation pattern behind Oath's inbox-analytics pitch — leaving independent senders dependent on whatever telemetry their recipients' provider permits.
The trend: Email is moving from sender-side surveillance via tracking pixels toward platform-controlled privacy defaults, with mailbox providers becoming the gatekeepers of what senders get to know.
