I absolutely need deep links. They’re how I process my email: sending tasks to OmniFocus and leaving nothing in the inbox.
You can do this in exactly five ways that I know of after researching this extensively
- Use Apple Mail. Downside: you can’t create the links on iPhone unless you use the now deprecated app Dispatch.
- Use Spark with those scripts on Mac. Downside: on iOS, Spark sends your emails to your task manager inbox, which is the dumbest thing.
- Use Newton. Downside: expensive, and sometimes character encoding goes wrong, but links work everywhere.
- Use Airmail. Downside: … it’s Airmail. (I have however a confession to make. I’m using it again. I know. But the deep linking scheme is the most robust on the market. If you’re willing to put up with Airmail being Airmail, then it’s the best solution on that front.)
- Use Gmail and design a shortcut to convert mail.google.com into the Gmail app URL scheme for iOS when you need to access them. I used to have one but I have not used Gmail in years so it probably does not work anymore, but it can be done.
