Is there a way to label an Email w/the word task, email it to myself and have it added to my tasks list automatically. I know I can open the email and add tasks but I'd like to do this via a filter rule.
No, this isn't currently possible. (support posting) The quickest way I've found is to create a filter that applies a label to these emails. Then, I am able to open up the label, use keyboard shortcuts to navigate and open an email, and then
shift+t will create a task for the opened email. Use a keyboard shortcut to get to the next email, rinse and repeat.
If a filter action to add to tasks is ever created, I'll just have to switch my filter action rather than creating a setup then.
