Apple's Mail app doesn't support this although there are probably options to have it handled via the Share sheet and use the Workflow app. You can use indeed third party e-mail apps such as Airmail, Spark, Dispatch, myMail see also.
That’s a really good tip. Didn’t know about it. All the known 3D touch command lists I’ve seen never mentioned this. Do you know of a comprehensive list anywhere? Anyhow, thanks for the tip.
Didn't know about this, either. I assume there's no solution for non-3D touch users. When I do a normal tap on the preview, it just gives me the options of skipping or stopping/starting at that page. Using the zoom gesture does nothing, too.
