This works fine on the iPhone Mail Beta 18.3 On the Mac it presents in a confused manner. Hi there, sorry for delayed reply. It's actually working pretty good. A bit of an inconvenience as once you set a reminder on an email you then have to move that email to a folder you create (I created Mail | Snooze). When the date for the reminder comes up, the email still shows in the Snooze folder I created but it also then shows at the top of my inbox. If I then decided to snooze that email again, it then automatically moves itself from my inbox and only shows in my Snooze folder. The only time that email will be removed totally from my snoozed folder is if I delete the email if I have actioned it in my inbox or I move it to another folder. Other mail programs do that process automatically (moving it to the snooze mail folder) and as you, I just don't understand why cannot do this. The other email apps I have used, I find that when I go on other devices (I use a Mac mini, iPad, iPhone and MacBook Pro, the snooze folders are never in sync but with the process I use above, my Snooze folder remains in sync. I keep coming back to mail even after using Outlook and Spark. I love Spark but too many times emails end up instead of in the snooze mailbox they end up in their set aside folder and this frustrates me. Apple Mail has always seemed to be a solid option (I use Google email with my own domains) but it really is lacking features. Right now with the betas of 18.3 the performance and presentation between emails on the iPhone compared to the Mac is not matched (Mac Mail to be updated still to match Mail Beta on iPhone) It should be noted also that the Mac Mail under Beta, what I have explained above on what I do, I only do that on my iPhone as if you try it on the Mac Mail beta, it will confuse you and not present as it shows on the Phone, it needs Mac Mail Beta to match the new features of mail on thee phone for the two to present the same way.
