Yosemite’s “Mail Drop,” with plain text emails, considered harmful. | Dan Wood: The Eponymous Blog
22 Nov 2014 • gigliwood.comThe problem is that if you use this technique, it’s possible that any actual textual message might not be seen by the receiver of the email message.
If you send your email message as plain text — you might not even realize that you are sending a plain text message or a rich text message —or if the receiver’s email client shows them plain text instead of rich text — then ONLY the Mail Drop URL will be seen by the receiver. Not your important message.
I know a lot of things about multi-part email encoding seem entirely arbitrary and insane but this implementation by Apple seems completely brain dead. Did plain-text email die completely and I just never got the memo? To me best practice is still to include both text and HTML content.
Seems like they could have included the plain-text content and then added the mail drop URL as a footer easily enough. Perhaps just an oversight?
