Sendproof.io gives you proof of delivery for every link and file you share. Get real-time notifications when recipients open your content, with detailed tracking including timestamps, location, and device info.

No more "I never received it" excuses โ know exactly when your important documents are viewed.

What to expect from an ideal product
- Sendproof.io sends you a real-time alert the moment a client opens your proposal link, so you know exactly when to follow up without guessing or pestering.
- Every open is logged with a timestamp, location, and device, giving you hard proof the file was delivered and viewed if a client claims otherwise.
- Freelancers use it to confirm invoices were seen before chasing payment, removing the awkward "did you get it?" back-and-forth from the process.
- Sales teams can see which proposals got opened, how fast, and from where, turning blind follow-ups into well-timed conversations backed by real data.
- No software to install on the recipient side, just share your link or file as usual and Sendproof.io handles the tracking silently in the background.
