I have been searching for a good cross-platform email client for a really long time. Here are my requirements and a few shortcomings of popular clients.
- At least available on Android, Linux, Windows 10.
- At least support both personal and organizational accounts for gmail and outlook.
- Email-accounts synchronization. I only have to set up my 6 email accounts in 1 device, and all other devices should have access to those accounts without any further configuration on other devices.
- Able to send, receive, forward, reply, delete, archive emails on all devices, which may contain image, file, hyperlinks and, very importantly, appointment/meeting/schedule invite.
- Outlook does not support Linux or accounts sync. It also has some problems with my gmail university account.
- thunderbird does not support sync. No Android.
Please let me know if clarification needed.
