Can privacy notices be sent electronically?

Excuse me, I was wondering if I could get your thoughts on a question related to privacy notices. Specifically, is it considered acceptable or even advisable to send these notices electronically, rather than through traditional mail? I understand that there are benefits to digital communication, such as speed and efficiency, but I'm also concerned about the security and privacy implications of doing so. Could you please elaborate on your stance and provide any insights or considerations that I should keep in mind when making a decision about this matter? Thank you for your time and expertise.
