Gmail and Apple Mail proxy and prefetch images, inflating every other tracker’s numbers. Readack classifies each fetch and scores its confidence — green means a real human opened it.
Wrapped links tell you exactly who clicked what — and per-recipient tracking shows which person in a group thread engaged, not just that someone did.
Mail is sent from your own Gmail. We never read your email bodies, never sell data, and store IP addresses only as salted hashes.
For trying Readack and light personal use.
Everything in Free, plus the full toolkit.
