After testing several platforms for sending large files, I can confidently say that Sinosend has exceeded my expectations. It combines ease of use, professional branding, and smart tracking, making it a well-rounded tool for sharing files with clients, colleagues, or partners.

✅ What I loved most:
Fast and reliable transfers: Uploading large files is quick and stable—even if your connection drops, Sinosend resumes without hassle.

Consistent branding throughout: You can customize email notifications, download pages, and even use your own domain (depending on the plan), creating a polished, branded experience.

Real-time tracking: Get alerts when files are opened, downloaded, or previewed—along with IP and geolocation data. Ideal for sales or follow-ups.

File requests made easy: Clients or collaborators can securely send you files using branded “Request” links—no account needed.

Unlimited in-browser previews: View images, PDFs, videos and more directly in your browser—no need to download everything.

Clean, organized interface: The dashboard makes file management a breeze, with quick searches and automatic ZIP downloads.

🛠️ What could be improved:
While the platform performs very well, the customization options could be more precise, intuitive, and comprehensive.
Most notably, the file upload screen lacks customization in key areas, which limits the branded experience at a crucial stage of user interaction.
It would also be fantastic to have more language options—or at least the ability to manually edit the interface for translation, making Sinosend even more global-ready.

🔍 Final verdict
Sinosend is a solid, professional, and practical solution for anyone who regularly shares large files and wants full control, branding, and tracking. It’s ideal for agencies, designers, sales teams, educators, or freelancers.

With real-time insights, a polished look, and an intuitive dashboard, it’s a smart investment.
The AppSumo lifetime deal makes it even more appealing.

Highly recommended!
