Ostra is email on mailostra.com infrastructure — for businesses that would rather their inbox said nothing louder than they do.
Ostra resists the instinct to add. Every part of it earned its place.
A layout with room to breathe, designed to slow you down in a good way.
Encryption that is simply on, with nothing to configure or explain.
Correspondence kept indefinitely, as a matter of course.
"There's a stillness to it. Everything is exactly where it should be."
Yes — Ostra is used by firms of one and firms of eighty alike.
It's kept, quietly, indefinitely, on every plan.
