Hands-on Experience / My Honest Opinion
I’ve worked in tech and digital content for over 10 years. I tried Sinosend for sending videos and big graphics to clients. It was easy to use. Uploads didn’t fail, even on my slow home Wi-Fi.
I loved the alerts. I knew the exact time a client opened a file. That made my follow-ups much smoother.
The look of my shared links impressed my clients. It felt pro. But the dashboard took me a bit of time to learn. And custom domains cost extra.
