However, sometimes the changes you make on one device may not reflect across all your devices.Ī common issue with Apple Mail is that sometimes it may use a local storage to store changes you made on different email folders, instead of your mail server. In an ideal case, you should be able to see the exact emails sorted in the same folders across your devices. The good thing is that, nowadays, you can set up your iPhone, iPad, and Mac to use any email provider of your choice, be it Apple Mail, Gmail, or whatever you use. If you want to take the least time checking and responding to emails, consider syncing your email accounts across all your devices.
