That is a terrible hack of a workaround and you know it :)
With Google Inbox (inbox.google.com) I can Snooze an email for [x] number of days and it'll be gone from my inbox and I don't have to think about it until it comes back. I use Inbox for personal email but I'd rather not be.
Airmail doesn't have a web client, and that's where most of my emailing takes place, so unfortunately it's not an option.
We use FrontApp on top of FastMail for customer service, it provides a bunch of useful features on top of email, such as the one I just mentioned. I could use it for my personal email but that would mean paying two monthly subscriptions. Plus it doesn't have spam filtering built in.

And... You've just lost standards compliance so you can't use any standards compliant clients. This is a terrible hack of a workaround and you know it :)
No I haven't lost standards compliance. The feature does not interfere with IMAP at all. Sure, I don't get the useful features with a standards complaint client, but why would I expect to?
* Create a folder 'On Hold'
* Move emails there
* Check in a couple days.
If you want alternatives, check AirMail. I find it's a good client on iOS and OS X that implements what you want
