What is the Chinese equivalent of the English morpheme 'e-' indicating "digitalization"? For instance, "email" (or "e-mail") is one that has been essentially canonized (e.g. it has been added to various canonical dictionaries), but what about other instances of the addition of this morpheme and its Chinese translation? Is there a general heuristic or rule for indicating digitalization in Chinese, analogous to the English 'e-'?

After a few attempts on Google Translate, it seems like the way to go is to preface the word with “电子” (which means "electronic") – this seems right, but are there exceptions I should know about?
As far as I know, there's no exception for translating "e-" to "电子" unless it doesn't indicate "digital" electronic.
