Here's a simple scenario I can't find any free solutions to:
- I am sending an email to a client to which I want to get a response within 3 days.
- If I get a response, I don't want to be bothered with false-positive reminders.
- If I don't get a response within those 3 days, I want a reminder reminding me to follow up on it.
I am using GMail (although I am willing to use a non-web based email client if all else fails).
That's all I am asking for and I can't find a free solution on the Internet.
