I’ve struggled for a while to find the ultimate email client. One would be amazing for my MacBook, but wouldn’t have an iOS counterpart. Astro does it all for me, no matter the device.
I understand some people’s misgivings for it not supporting many account types, but as I only use G Suite accounts it isn’t an issue for me.
It’s easy to use, very clean, searches fairly quickly, tracks email opens, assists with unsubbing, suggests useful things like VIP contacts, and more, all for free no less.
A couple things I’d love to see in updates:
1. Customizable account icons - many are the same color for me, which makes it meaningless. Custom icons would help make that useful to me.
2. Track which recipients open emails. This is a feature I’ve come across other platforms but not here. While it tells you if an email was opened, it doesn’t tell you who opened it.
3. Show all account boxes in the sidebar. Right now I have to tap the top arrow, then tap which inbox I want to open. It’d be nice if all inbox titles show up in the sidebar all the time.


Finally, an app that replaced Outlook! The read receipt won me over. As a devout iPad user I look forward to seeing what you can do with a calendar app.

Thank you!
