MailTrack

MailTrack works inside the normal Gmail screen to show whether a sent message has been read. It marks emails with checkmarks in the inbox, so there is no separate application to open. The aim is to help people time their follow-ups more accurately.

What MailTrack offers

• Read receipts — one checkmark means sent, two mean the email was opened.
• Open counts — shows how many times a recipient viewed a message.
• Click tracking — counts clicks on links in the email.

Who it works with

Gmail users who send emails where a reply matters, such as sales and recruitment outreach, and who want to time follow-ups by seeing whether a message was actually read. It needs no separate application.
