Stick it to an email
Everyone else can put stuff in your inbox, but you can’t. But with HEY you can. HEY lets you add personal sticky notes to any email in your Imbox. They’re great for jotting down phone numbers, dates, addresses, links, and personal, private thoughts you’ll need next time you reference that email.
Can other people see these notes?
Nope — these are just for you. They’re entirely private. No one else can see a sticky note on your email in your inbox.
Do these notes show up on the email thread themselves?
No, Stickies only show up in the Imbox.
