Been there. After a few mishaps myself, I started looking into alternatives. I found digital faxing through
ask4research.info
and it’s honestly solid. You can send files securely with encryption, get a confirmation when it’s delivered, and avoid all the email headaches. It doesn’t rely on traditional fax machines either — it’s fully digital. For anything sensitive, I now skip email completely and just use digital fax. It’s safer, cleaner, and works without the mess of attachments or bounced messages.
