Mail Seen - Unlimited Email Tracker for Gmail

Did not work for me. Sent an email to two people. One saw it on their iPhone. The tracker registered the event. Another person saw it on their Samsung phone. The tracker registered the event as seen from a Windows Phone. The tracking of the first person who saw it on their iPhone was lost.

I'm unable to cancel my subscription! No help, no settings, no option for deactivation and mails are not replied.

1-star only because it says it's free, and after install it says free user is up to 10 tracked emails.

This did not work. I have sent 3 emails to 3 different people that opened and viewed it. It did not show that the emails had been viewed.

Not working. I sent mail from my Gmail to outlook mail & Gmail to Gmail but it's still showing " Nobody saw this email yet ". but I already opened that mail. Also i do multiple refreshing over my Gmail but still same result.

I have subscribed to the Mail Seen - Unlimited Email Tracker for Gmail - Premium Version. Regrettably, I am facing multiple issues that necessitate your urgent attention. At this moment, the tracker appears to be either disabled or malfunctioning, and I am unable to find your contact information. I would greatly appreciate your prompt assistance in resolving these matters.

It was working fine, then the events reset to zero and I am not sure if it is still tracking the old emails that I sent and/or it has stopped working. Also, it would be good to be able to choose which emails I want to track and emails that I don't want to track. Thanks

its better then i expected i guess, not really liking how it sends 10 of same email, or doesn't notify me or tell me much.
