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 — it does not handle trackers other senders embed. Mailshade is the dedicated option for the web client: after you opt into mail.superhuman.com, Chrome's declarativeNetRequest cancels requests to known tracker-pixel domains before they load. A local DOM scan detects pixels and supported tracking-link patterns; recognized links offer a direct-or-original choice. The dashboard records detected tracker occurrences by sender. This guide explains the limits of Superhuman's setting and what network-level known-domain blocking adds.

Superhuman's built-in setting and its limits

Superhuman can hide read statuses, but the control is scoped to its own behavior. It does not block every tracker another sender can embed.

Adding Mailshade on Superhuman

  1. Install Mailshade and opt into Superhuman.
  2. Open mail.superhuman.com.
  3. Open a tracked message; requests to known tracker-pixel domains are cancelled via DNR.
  4. Use the red-eye overlay and dashboard to review what the local scan detected.

Dedicated coverage

Mailshade treats Superhuman as a first-class client and adds known-domain network blocking there.

Link choice

For a supported tracking-link pattern, Mailshade shows the direct destination and original URL. You choose which one to open.

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; Mailshade adds known-domain network 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?

Core protection remains free after a 14-day Pro trial. Paid Pro starts at $3.99 per month or $19 one-time for Founders Lifetime, with the same pricing across clients.
