I wrestled with this same issue when I was working corporate and limited to Outlook on desktop. Let’s be honest – there just aren’t any mail clients on Windows that pull their weight against Outlook.
That’s part of the reason I made a script to Capture OmniFocus Tasks on Windows with AutoHotKey. But that’s not for everyone.
Question 1 - Do you have the ability to use a software like Spark on your iOS device to snooze emails, or is that restricted by IT policy? Snoozing could be helpful feature to keep email tasks in email.
Question 2 - How are you handling email process-wise? There may be a better way to handle it based on your process versus tooling.
For example, I tried to limit processing email to three times per day, which was really to help stay out of email all day. But during those processing sessions, I’d make sure to reply to every email, even if it was “Hey, I got this. I’ll work through this later this week and get back to you.”
The key that helped me there was not clipping emails to OmniFocus, per say, but rather adding tasks. If I wasn’t able to fully reply to an email during a processing session (which I did not limit to the GTD 2 minute rule, by the way), it usually meant there was an additional task I needed to complete, something like filling out a form, thinking through an idea, or something of the sort. That’s what I’d save to OmniFocus, which makes a lot more sense.
You could tag items like this in OF “From Email” or something like that to make sure you have them in a single list. And you could review it every week to make sure it’s cleared out.
During my processing sessions, if I wasn’t able to get to an email, I’d simply leave it in the inbox. I’d always start from oldest to newest.
