Edison Mail Privacy: Does Edison Track Your Email?
Edison Mail strips senders' spy pixels. It also pulls purchase data from your receipts for a research business, and it now belongs to the alternative data firm YipitData. Here is what it blocks, what it collects, and what that means for Gmail in a browser.
Edison Mail privacy is a strange story, because the app sits on both sides of it. Its features page promises to "Evade Email Tracking Pixels by Default." No marketer learns from Edison that you opened their newsletter. Edison itself learns what you bought: its privacy policy says it scans connected inboxes for "Commercial Data" and passes anonymized versions to business subscribers. So does Edison track your email? Not the way Spark or Polymail do. It does something different.
Key Takeaways
- Edison Mail offers no sender side read tracking in its free app or in Edison Mail+, and it strips invisible tracking images from incoming mail by default.
- Motherboard reported on February 10, 2020 that Edison extracted purchase information from users' email receipts and sold insights through Edison Trends to clients in finance, travel and ecommerce.
- Edison's privacy policy, updated September 23, 2026, calls Edison "an affiliate of Yipit LLC (d.b.a. YipitData)" and allows sharing anonymized commercial data with YipitData and business subscribers.
- A server side update on May 15, 2020 let about 6,480 Edison Mail iOS users read and send email from strangers' accounts until Edison pulled access the next morning.
- Edison's pixel blocking only works inside the Edison app, so Gmail users who read mail in a browser get none of it.
Does Edison Mail Let Senders Track When You Open Their Email?
No. We found no feature in Edison Mail that lets a sender see opens, clicks or read receipts on the mail they send. The Edison features page lists undo send, block sender and spy pixel blocking, among others. The paid tier, Edison Mail+ at $14.99 a month, adds sender verification and caller ID, not read tracking.
Other clients in this series work the opposite way. Spark's Read Statuses plant a pixel in outgoing mail for paying Pro users, and Polymail logs opens, clicks and downloads as its headline feature. An email from an Edison user carries no Edison tracker into your Gmail. Mailbird does both: Mailbird email tracking lets Premium users see who opened their mail, while Mailbird Next blocks incoming pixels by default.
How Does Edison Mail Block Read Receipts?
Edison deletes tracking images from the message before you see it. Its blog post Don't Use Email Without a Read Receipt Blocker says the app "detects invisible images or videos based on their unique pattern and we remove them from the email body before the email is opened," which "removes invisible pixels to prevent sending http requests to the tracking server." It is always on, and Edison's secure email page says it works "without disabling images."
This is stripping, not proxying. Apple and Proton fetch remote images through their own servers so the sender never sees your IP address; Edison's documentation describes no proxy. Our reading, which nothing Edison publishes confirms or denies, is that images it judges harmless load straight from your phone, IP address attached. A tracker disguised as a visible logo would pass the same way.
Edison's marketing overreaches, too. The features page claims "More than 8,600 spy pixels are hiding in your inbox every year. Edison Mail blocks every single one of them automatically." Pattern matching cannot promise that, and Edison publishes no method behind the figure. We also found no Edison page on tracked links, the redirects that log what you click. Our guide to blocking click tracking in Gmail explains why pixels are only half the problem.
What Does Edison Do With Your Email Data?
Edison scans connected inboxes for commercial messages, from purchases to boarding passes, and turns them into anonymized research data. The current Edison privacy policy, last updated 9/23/2026, says: "We process emails collected through the Services to identify those related to commercial activities." It continues: "We may disclose De-identified Data to our affiliates, including YipitData, for commercial research, analytics, products, and insights offered to business subscribers."
On February 10, 2020, Joseph Cox at Motherboard reported that a J.P. Morgan document described Edison supplying "consumer purchase metrics including brand loyalty, wallet share, purchase preferences, etc." sourced from "the Edison Email App." Edison answered the same day, according to MacRumors, that it "measures e-commerce through a technology that automatically recognizes commercial emails and extracts anonymous purchase information from them" to keep the app free without ads.
Two more facts complete the picture:
- Humans have read the mail before. In July 2018 the Wall Street Journal reported that Edison employees "reviewed the emails of hundreds of its users" to build a feature, per Engadget. Edison said its user agreement covered it. More in Does Google Read Your Email?.
- The owner is a data company. Edison announced on September 22, 2021 that it had been acquired by Yipit, which it described as producing research reports from "de-identified and aggregated data, with a focus on public companies."
Apple's App Store listing agrees: its privacy label lists Purchase History and "Emails or Text Messages" as collected data, and the description says commercial emails "are stored to deliver Edison Mail Assistant features built into the Email app and Edison Trends."
Can You Opt Out of Edison's Data Collection?
Yes, partly. The privacy policy says "You can ask us not to provide certain information to our business subscribers via the 'Manage Privacy' page." In 2020 Edison told MacRumors the path was Account, then Settings, then Manage Privacy. Edison's Privacy Commitments page says you can "delete stored data or opt-out of our Trends product anytime, without losing any of the functionality."
Read the wording closely. Opting out stops Edison providing data to subscribers; the policy does not say it stops Edison processing your commercial emails, which also power the app's Assistant features. The September 2026 policy also still points users to "OnMail settings" for the opt out, although OnMail closed in 2025. A small error, but a telling one.
The 2020 Bug That Opened Strangers' Inboxes
On Friday, May 15, 2020, Edison shipped what it later called "a server-side update to a feature that allows iOS users to manage accounts across their Apple devices." According to Edison's own incident post, the result was that "User A and User B could access each other's accounts connected to Edison Mail for iOS." About 6,480 iOS users were potentially affected; Android and Mac users were not.
Affected users could read and send mail from a stranger's account, as MacRumors reported at the time. Edison says no passwords or credentials were exposed. A Saturday morning patch cut affected users off from their mail, a full fix followed Sunday, and Edison told them to change their passwords. This was not a hack. It was a sync change that mixed up whose account was whose, a risk that comes with any client syncing account access through its own servers.
What Happened to OnMail?
OnMail, Edison's separate email service, shut down on July 31, 2025, according to Spam Resource. At its April 2020 launch, TechCrunch highlighted its sender approval controls and tracking pixel removal. Edison Mail itself continues, with App Store version 26.9.1 shipped in September 2026.
What This Means for Gmail Users
It depends on where you read your mail. If you connect Gmail to the Edison app on your phone, Edison's pixel stripping applies to every message you open there, and your commercial mail also enters Edison's research pipeline unless you opt out. Gmail's image proxy belongs to Google's own apps; as far as we can tell, a separate client loads images on its own terms.
If you read Gmail in Chrome, Edge or Brave on a laptop, Edison does nothing for you. A phone app cannot strip a pixel from Gmail in your browser, and Gmail's own protection is narrower than people assume. Google's image help page says "Senders can't use image loading to get information about your computer or location," then concedes: "Sometimes, senders may know whether you've opened an email that has an image." Our explainer on how Gmail read receipts work covers why.
Most coverage treats Edison as either a privacy app or a data broker. It is both. Pixel blocking keeps one sender from learning that you opened one email. The research business turns what users bought into signals for J.P. Morgan clients. Blocking one does not offset the other: privacy is never one feature.
Edison vs Gblock vs Apple Mail vs Proton and HEY
Every option below stops some tracking, and none covers all your devices at once.
- Edison Mail: free, on by default, strips invisible pixels without breaking other images. Limits: only inside the Edison app, no documented proxy or link cleaning, and the app funds itself with anonymized purchase data unless you opt out.
- Apple Mail Privacy Protection: per Apple, it hides your IP address and downloads remote content "in the background when you receive a message (instead of when you view it)," so opens become meaningless. Limits: Apple's Mail app only, not the Gmail app or Gmail on the web. See how Apple Mail fakes email opens.
- Proton Mail: Proton's documentation says tracker protection is on by default, removes known trackers, and loads other images "using a proxy with a generic IP address." Limits: it protects Proton addresses, so you have to move your email.
- HEY: its spy pixel blocker "blocks these trackers and tells you who's spying on you." Limits: a paid, separate email service, not a layer over Gmail.
- Gblock: a browser extension that blocks tracking pixels and strips link tracking inside Gmail on the web, with an automatically updated blocklist. It flags unknown images of 150 bytes or less, and custom filters let you block any host yourself. Limits: desktop browsers only, not the Gmail mobile app or a client like Edison, and a never seen pixel can slip through on first open.

How to Block Email Tracking Without the Data Trade
To keep the pixel blocking, drop the data trade and cover Gmail on the desktop:
- Opt out in Edison. Open the Manage Privacy page in the app's settings and decline sharing with business subscribers, as the privacy policy describes. Edison's Privacy Commitments page says you can also delete stored data.
- Consider Apple Mail on iPhone if the research model bothers you more than the pixels. It proxies remote images through Apple's servers and hides your IP address.
- Turn off automatic images in Gmail on the web. Per Google: Settings, See all settings, Images, "Ask before displaying external images," Save Changes. Every image, tracker or not, waits for your click.
- Add a pixel blocker in your browser so images keep loading while trackers do not. Edison cannot reach that gap.
The Quick Answer
Edison Mail does not track your email opens. On Edison Mail read receipts, the app works the other way: it blocks senders' receipts by stripping invisible pixels inside its app. It does scan connected inboxes for commercial mail and shares anonymized data with its owner YipitData and business subscribers unless you opt out under Manage Privacy. None of its protection follows you into Gmail in a browser.
BlueMail, another free cross platform client, takes a different approach: its BlueMail read receipts use the standard request your mail app can refuse, but its mobile push servers still handle your login.
