Know the moment they open.
Mail Pixel tells you in Slack — and on your phone — the moment someone opens your email.
No inbox access · No IP logging · No branding on your emails
Three steps. Nothing to learn.
Install the extension, then send email exactly like you always have. Mail Pixel does the rest.
Send from Gmail
Nothing to change — send exactly like you always do.
We catch the open
A single invisible pixel tells us the moment it loads.
Slack + phone ping you
First open, every open — no dashboard-watching required.
Built to be trusted with your inbox
Tracking tools have a reputation problem. Mail Pixel is built the opposite way.
Only the subject and recipients of mail you send are recorded — never your inbox or attachments.
Opens are recorded; addresses are salted and hashed before they touch disk.
No visible branding, link, or footer on your outgoing messages.
Free for everyday sending.
