Spark for personal and Outlook for work. Really wish Outlook had the option to show pinned emails at the top like Spark does though.

Most email apps on iOS and macOS route emails through their private servers which is a security risk. This risk magnifies when one has also set up their work accounts on their devices.

Also, many email apps cater to Gmail, which I understand is the most popular email service, but prohibits me from using with my accounts.

Therefore, the native, default mail clients on both platforms is what I use.

Do let me know if there are email clients that do not reroute one’s emails. I would love to try those out.

i tried some of the clients but neither satisfied me like gmail does.

The search, the functionality and also the swipe behavior of the native apple client is way worse then the gmail client. This also terminated the use of an icloud mail adress, so I forwarded this to my gmail.

I also do not want another account for my email client just to access my mails, so most of the other clients were out of the race. In the end I stick to my gmail account and it's app, cause it satisfies me the most.

Thanks again for all your answers :)

Some of the Google Inbox people did rebuild Inbox as "Shortwave" https://www.shortwave.com/blog/introducing-shortwave/

Which is available as both an iOS app and PWA. For those unaware, Outlook is also becoming a PWA.

I just wish the IMAP standard would expand to include contacts and calendar.

Going to show my privilege here and say Superhuman. It’s expensive as hell, but if you’re like me and email is a major part of your job, it may be worth it. I can get the gmail web client to do about 90% of what Superhuman does, though. So for an economical version, perhaps look up a guide on how to setup and use the Gmail web interface with nothing but a keyboard. In my experience, taking the time to learn how to navigate your inbox in this way pays dividends down the road. Good luck!
