Attach files from iCloud drive, Dropbox, Google Drive, One Drive etc. and HTML signes
Easily atach files from all of the best known cloud drives just directly from the Airmail app.
Then support for HTML email signs just like in the Airmail for MacOS :-)
Plz use ELEPHANT DRIVE ALAO
This feature should enable either sharing of a weblink to that file (as is the norm with cloud services), or somehow pulling that file and embedding it directly into the email.
Outlook on iOS has some great ideas, currently my go to app. Neat how easy it is to attach files from recently received emails, to a new email being written.
