Do you work late at nights? Are you the one who would have a sleepless night if you had to send in a mail at 7am? (yes, the time stamp matters). Well, Right Inbox allows this if you're a Gmail user. You can schedule exactly the time at which you'd like to send your mail. The feature is free during its entire open beta phase. Right Inbox also allows you to send yourself a future Email as a reminder.In a recent announcement, Right Inbox now allows to track Emails! After installing the browser extension, when you go to your Compose screen you will notice an additional button labeled as Track. You may use that check-box button before you send an email to track the mail. When the recipient opens your Email, you will be notified by another email instantly.
These are the kind of products that get you addicted to them so much that as soon as they're priced, you can't stay away from them. You'd be ready to pay for the feature and once that happens, the makers can truly stamp themselves with the confidence that they've made something 'useful'.
