Whichever task manager I use, I heavily rely on email reminders. I might or might not have this task manager opened, or with me on my phone. But email is always there.
So due dates in Dynalist without email reminders are pretty useless for me.
If you consider adding this feature, please note that it is only useful if you send a separate reminder for each task at it’s due time. Not a single email with “all your tasks for today”.
