Aero vs. HEY
The same ideas, without the new address.
HEY rethought email from the ground up: screen your senders, give newsletters and receipts their own place, and keep the inbox for people.
Aero owes a lot to that thinking.
The difference is that Aero does it inside the account you already have.
No new address, no forwarding, no telling everyone where to find you now.
Comparison
A new inbox, or a new address?
HEY is a complete email service. You get a hey.com address, and the whole experience is built around it. Moving in means moving.
Aero is a client for the Gmail or Outlook account you already use. The screening, the separate lists, and the smaller inbox — layered onto the address you already have.
