Sending a file is only half the job — knowing it was actually received and reviewed is the other half. Sinosend’s Delivery Intelligence layer gives you a live, detailed picture of every interaction with every transfer: who opened it, where they were, what they downloaded, and when. For global trade, where a missed document can delay a shipment or void a contract, that visibility matters.

​
Real-time alerts

The moment a recipient opens your transfer link or downloads a file, Sinosend notifies you. Alerts arrive via:
  • Email — an immediate notification to your registered address with the recipient’s name, the transfer title, and the timestamp.
  • Dashboard — the activity feed in your dashboard updates instantly, showing the event alongside the transfer.
You can customise which events trigger an alert under Settings → Notifications. Choose from open events, download events, or both.

​
Pending vs Viewed status

Every transfer in your dashboard carries one of two status indicators:
StatusMeaning
PendingThe link has been sent but no recipient has opened it yet
ViewedAt least one recipient has opened the transfer link
You can see these statuses at a glance in the Transfers list, making it easy to identify which items need a follow-up without opening each transfer individually.

​
Geo-location map

Each transfer has a Delivery Map panel that plots every access event on an interactive world map. For each event you can see:
  • Country — the country from which the file was accessed.
  • Region / state — a more granular breakdown within the country.
  • City — the specific city, where IP data is precise enough to resolve it.
This is particularly useful for verifying that a document reached its intended destination. If you sent a certificate of origin to a customs broker in Hamburg and the map shows an access event in Frankfurt instead, you know to follow up.
Geo-location is derived from the recipient’s IP address. VPNs or corporate proxies may cause the reported location to differ from the recipient’s physical location.

​
Access timeline

Click into any transfer to open the full Access Timeline — a chronological log of every interaction, displayed as a visual feed. Each entry shows:
  • Event type (opened link, downloaded file, previewed file)
  • Exact timestamp (date and time in your local timezone)
  • Recipient identity (email address and avatar)
  • Company affiliation (resolved automatically where available)
  • Location (city and country)
The timeline gives you an auditable, court-admissible record of document delivery — useful for compliance, dispute resolution, and internal reporting.

​
Company affiliation and avatars

Sinosend enriches each access event with the recipient’s company affiliation and avatar where it can resolve them. This means your timeline shows entries like:
Li Wei · Shenzhen Pacific Freight Co. · Downloaded Bill of Lading v3.pdf · Shenzhen, China · 14 Jan 2025, 09:42
Having company context makes it faster to identify who in a supply chain has reviewed which document, especially when multiple people from the same organisation are accessing the same transfer.

​
Automatic reminders

If a recipient has not opened a transfer within a set period, Sinosend can automatically send them a reminder email on your behalf. To configure reminders:
1

Open the transfer settings

Go to Transfers in your dashboard, find the relevant transfer, and click the ⋯ menu, then Settings.
2

Enable automatic reminders

Toggle Send automatic reminder to on. Choose the delay — for example, remind after 24 hours, 48 hours, or 72 hours with no open event.
3

Save

Click Save. If the transfer remains unopened past the threshold, Sinosend dispatches the reminder automatically. You receive a copy in your notification feed.
Automatic reminders are especially valuable for time-sensitive trade documents — letters of credit, inspection approvals, or compliance filings — where a delay in acknowledgement can have real financial consequences.

​
Expiry extension requests

Recipients can request a 24-hour extension if a transfer link expires before they have had a chance to download everything. Here is the flow:
  1. The recipient lands on an expired transfer page and clicks Request Extension.
  2. You receive an email and dashboard notification with the recipient’s name and the transfer they are requesting access to.
  3. You click Approve (or Deny) directly from the notification or from the transfer detail page.
  4. If approved, the transfer becomes accessible again for exactly 24 hours.
You remain in full control — no extension is granted without your explicit approval.

​
Dashboard analytics

The Analytics section of your dashboard gives you a high-level view of your sending activity:
MetricDescription

Total opensUnique link-open events across all transfers
Total downloadsIndividual file download events
Open ratePercentage of sent transfers that received at least one open
Download ratePercentage of opened transfers that resulted in a download
Use the date range picker to analyse performance by week, month, quarter, or a custom period. Export the data as CSV for inclusion in reports.
