Unless you're looking to import it as a task, I never understand the urge to move email from one place to another. Archive and folders should be enough. If there's any text you need to work with--how often does that happen?--there's cut and paste.
I would prefer Notion to have it, of course--same thing with scanning. But the workarounds are not terrible.
After years and years of being disappointed with Evernote--what exactly have they been doing for the last two years, during the revolution in personal workspace?--I couldn't be more thrilled with what Notion has done for me.
