Mailshade and PixelBlock compared

PixelBlock's current Chrome Web Store listing describes a focused Gmail extension that blocks email tracking attempts and shows a red eye when it finds and blocks one. The listing records version 2025.12.01, updated December 1, 2025. Mailshade 1.1.0 targets a broader workflow: six opt-in webmail integrations, declarativeNetRequest rules for reviewed tracker endpoints, in-inbox detection, supported tracking-link warnings and local sender-level history. The PixelBlock listing does not link to a public source repository, while Mailshade makes source archives and checksums available; reviewers must match an archive to the exact tested package version. That is an auditability distinction, not efficacy evidence. Ratings and user counts change frequently and are deliberately excluded from the conclusion. The two pinned builds have not yet completed the same controlled fixtures, so claims about protection rate, link behavior, benign-image breakage or overall superiority remain pending. Gmail-only users may value PixelBlock's narrow interface, while people who use several webmail services may value Mailshade's declared scope.

Versions in scope

  • Mailshade: 1.1.0 — Current public Chrome Web Store version confirmed on 2026-08-19.
  • PixelBlock: 2025.12.01

Method and current result

Each pinned extension must run in a clean Chrome profile against the same versioned pixel, link and benign-content fixtures before comparative performance is stated.

Current versions and publisher-stated scope are sourced, but no blocking-rate, false-positive or overall comparative result is claimed before the shared run.

Claim evidence

  • [verified] PixelBlock 2025.12.01 is described by its publisher as a Gmail extension that finds and blocks tracking attempts. source 1
  • [verified] Mailshade 1.1.0 is the current public Chrome Web Store version. Mailshade also makes source archives and checksums available, which must be matched to the exact tested package version; PixelBlock's listing does not link a source repository. source 1, source 2, source 3
  • [pending] Relative Gmail blocking recall and false-positive behavior remain unmeasured under the shared methodology.

What PixelBlock documents

The official listing is concise: PixelBlock is for Gmail, blocks email tracking attempts and displays a red eye when it finds and blocks one. This page no longer describes PixelBlock as warning-only or repeats an outdated rating.

What Mailshade documents

Mailshade declares six opt-in webmail integrations, reviewed endpoint DNR blocking, local detection history by sender and a choice before following supported tracking redirects. Mailshade separately makes source archives and checksums available; reviewers must match an archive to the exact tested package version.

Differences a source review can establish

  • Scope: PixelBlock names Gmail; Mailshade names six webmail integrations.
  • Audit surface: Mailshade publishes source archives and checksums; PixelBlock's current store listing does not link a public repository.
  • Reporting: PixelBlock advertises a red-eye marker; Mailshade additionally advertises local sender-level history.

What still needs measurement

A store description cannot prove tracker recall, request cancellation or false-positive behavior. Those outcomes stay pending until both versions run against the same network-observed corpus.

FAQ

Does PixelBlock block or only mark tracking attempts?

Its current Chrome Web Store listing says it blocks email tracking attempts and displays a red eye when it finds and blocks one.

Does PixelBlock support webmail outside Gmail?

The official listing describes PixelBlock as a Gmail extension. Mailshade declares opt-in integrations for six webmail surfaces, but benchmarked multi-client behavior is still pending.

Is PixelBlock source code publicly linked?

The current Chrome Web Store listing does not link to a public source repository. Mailshade makes source archives and checksums available; reviewers must match an archive to the exact tested package version. This page does not infer behavior from that difference.

Which product blocks more Gmail trackers?

There is no shared-corpus result yet. That question requires network observations from the same fixtures, Chrome version and comparable settings.

Why are store ratings omitted from the conclusion?

Ratings and user counts change daily and measure user sentiment rather than blocking efficacy. The dated source record can still be checked directly through the listing.
