Yesware

Yesware notifies me whenever my emails are opened by the receiver. It's the main thing i need from a email marketing software. Yesware works a better hand with gmail and it doesn't need any other screen to be opened separately for checking the notification. And it locates the receivers and the type of device he used it for checking the email.

Yesware notification will annoy most of the users since if you're sending hundreds of emails then your screen will be filled with hundreds of notification. It can be turned off but it won't strike at the moment of installing the yesware application so one definitely get annoyed by the notification.

Yesware gives us the time when the email is opened so we could make further progress by knowing that our recipient is aware of our services and if the recipient has opened more than once then we can say he is interested in our services. And we don't have to annoy the recipient by constant emails whether he has received our email or not.
