Back in the day, online chatting, messaging, and e-mail sending was somewhat of a pain. Most services worked well, that was not the problem. The issue was that you never knew when or if your messages were read by the other person.
Nowadays, apps such as Facebook Messenger or WhatsApp have this feature implemented. If you want the same feature when it comes to e-mails, then you can use Mailtrack.
You no longer have to wonder if people have opened your e-mails or not. With this web browser extension, you will be able to see if people actually viewed them.
The way it works is very simple. You just install the add-on and that's it. Then when you go to your Sent folder from your e-mail account, you will be able to see if they were read.
The program uses two check marks, similar to those from WhatsApp. The first one turns green when your e-mail is successfully sent and the second one does the same when the e-mail is viewed.
The whole concept of the extension is very useful, being something many people have dreamed of but thought wasn't going to happen.
However, it does have a downside to it, as the add-on only works with Gmail. If you are using Yahoo, Hotmail or any other e-mailing service, you will not be able to use Mailtrack.
I guess that if you've heard of this extension before you created an e-mail address and are interested in using it, it can help you decide which service you want to use. But creating another account just to be able to use this isn't something most people are willing to do.
Being able to see who read your e-mails and tell when people simply do not want to reply back can be very useful. As long as you are a Gmail user, Mailtrack can come in handy for you.
