## What it is
MailTrackerBlocker is a mail bundle plugin and extension for Apple Mail on macOS that strips email trackers, read receipts, and spy pixels from HTML emails before display. It labels who is tracking you so you can view images privately without disabling remote content.

## Use cases
- block spy pixels in Apple Mail
- find out who is tracking my emails
- read email newsletters with images but without trackers
- block read receipts in macOS Mail
- avoid disabling load remote content in Mail
- strip email tracking pixels from HTML mail

## When to choose
- you use Apple Mail on macOS 10.11 through 13.x and want images displayed while blocking trackers
- you want to know which companies embedded trackers in your email
- you prefer a native Mail plugin over switching email clients

## When to avoid
- you use macOS Sonoma 14 or newer, which dropped legacy Mail plugin support (use the extension version instead)
- you use a mail client other than Apple Mail
- you need tracker blocking on iOS or other platforms
