Reminder on an e-mail to re-open emails I sent

It would be great to set a reminder on an e-mail! -> FLAG like in Outlook!

To set a task reminder is not the same: When I get the reminder I cannot open the email I sent (for writing email again).

Reminder of emails which opens email I sent is necassarry because
so many people don’t answer and it is an easy way to resend an
old email!!

Hi, you can create task or event from email, nothing more is possible or planned at this moment.
Right click on email - create Meeting/task from email.

Of course if people will request this then we might consider it, but at this moment it is really not planned.
