As answered by people managing Mailtrack and demonstro.
Mailtrack's answer
Mailtrack puts email tracking inside Gmail rather than in a separate tool:
It all happens in the inbox itself, so there's no dashboard to open and nothing to learn. It has worked this way since 2013, and unlimited tracking has always been part of the free plan.
Mailtrack's answer
Because it has a track record few tools in this space can match.
When you're relying on a tool to tell you whether an email was read, how long it has been doing that reliably matters.
Mailtrack's answer
Mailtrack launched in 2013 in Barcelona, built around a single question people kept asking about their own email: did they read it?
More than 14 million people have signed up since, and over 3 million have the extension installed today.
The company behind it is Mailsuite, which also builds mail merge, templates, documents and eSignature for Gmail. Mailtrack remains the tracking product and the name most users know.
