How to block email tracking on Superhuman
Superhuman includes a built-in option to block read statuses, but it is off by default and only governs Superhuman's own surface — so most users never enable it, and it does nothing for the trackers other senders embed. No standalone tracker blocker covers Superhuman either; they were all built for Gmail. Mailshade is the dedicated option here: it runs on mail.superhuman.com and uses Chrome's declarativeNetRequest to cancel known tracking-pixel requests at the network layer before they load, so the open is never reported. It also unwraps click-tracking redirect links and records each blocked sender in a local dashboard. This guide explains the limits of Superhuman's own setting, how to add network-level blocking on top of it, and how to confirm tracking is actually being stopped in the Superhuman web client.
Superhuman's built-in setting and its limits
Superhuman can hide read statuses, but the control is off by default and scoped to its own behaviour. It does not block the marketing, sales and recruiting pixels that arrive in your inbox, and it does not cover any other client.
Adding Mailshade on Superhuman
- Install Mailshade from mailshade.org.
- Open Superhuman on the web at mail.superhuman.com.
- Open a tracked message — the pixel request is cancelled via DNR before it fires.
- Check the red-eye overlay and the dashboard to confirm the block.
Why a dedicated blocker matters here
Because no other standalone blocker supports Superhuman, enabling network-level blocking is the only way to stop sender-side trackers there. Mailshade treats Superhuman as a first-class client, not an afterthought.
Keep the speed, drop the trackers
Mailshade blocks only known tracker domains, so Superhuman's images and interface are unaffected — only the covert pixel and click tracking are stopped.
FAQ
Does Superhuman block email tracking on its own?
Superhuman has a built-in read-status setting, but it is off by default and only affects its own surface. It does not block the tracking pixels other senders embed, which is what Mailshade handles.
Is Mailshade the only tracker blocker for Superhuman?
It is the dedicated option. Standalone rivals like Ugly Email, PixelBlock and Trocker do not cover Superhuman, so Mailshade is effectively the way to add network-level blocking there.
Does Mailshade work in the Superhuman desktop app?
Mailshade is a Chrome MV3 extension for the Superhuman web client at mail.superhuman.com. It does not run inside a separate desktop wrapper that lacks extension support.
Will blocking trackers slow Superhuman down?
No. declarativeNetRequest rules are evaluated by the browser without scripting each request, and Mailshade blocks only known tracker domains, so Superhuman's responsiveness is unaffected.
How much does Mailshade cost?
Paid plans start at $3.99 per month or $19 one-time for Founders Lifetime. Pricing is the same for every client and is listed at mailshade.org.
