Designers should favour allowing users to undo a delete operation over confirming it (e.g. GMail lets you undo e-mail deletion instead of asking if you are sure).
What would you call such operation in general? I have used an undoable operation term but then I realized that undoable really means an operation that can not be done.
I have came up with cancellable operation then but I feel it is not the same. Now it looks like the operation has already been started and can be interrupted by cancelling it – which is not true.
So – what would you call an operation you can undo?

When you undo an operation in Gmail, for instance, the state of the mail program is reverted by reversing the most recent user action. Therefore, one suggestion to describe your "undo-able" set of operations is:
Reversible — M-W
or revertible — Wiktionary
