Liking the Apple Mail App
What I’ve realised after using the native Mail app for so long is that actually, what is most important to me is just having all of my email accounts in one place and being able to view all of my inboxes at once via one main inbox. The Mail app does this fantastically in my opinion.
If the Mail app wasn't so notoriously bad at syncing and delivering notifications, I'd have used the Mail app too. Now, I've given up on generic email apps altogether recently, but I agree with Charlotte here, Mail seems to work really well for a lot of people.
