A no-account tool that generates hosted tracking pixels and a private activity link for monitoring image requests in emails.

Landing page captured for the 2026-09-21 issue.
For
People testing email image delivery and request activity
Worth noticing
Pixels expire after 30 days and each has a separate private management link.

Field notes

The page creates an opaque image URL, an HTML snippet, and a separate private management link, with activity access saved in the current browser profile. It states that valid image GET requests receive server timestamps, while pixels expire after 30 days and are subject to a request cap. Gmail is handled as a separate extension workflow because ordinary compose does not accept raw HTML.
