Mailtrack is an email tracking extension for Gmail. When you sent a mail to anyone and you need to be sure that your mail has opened on time or not Mailtrack lets you know if the emails you’ve sent have been read or not.
Thank you for reading this post, don't forget to subscribe!A single check means that the mail you have sent has been delivered but not opened. Double Check means mail has been delivered and opened by the recipient.
But if you sent mail to more than one person then the free version of Mailtrack does not provide notification for that mail, for that you have to take a yearly subscription.
