The user needs to resolve an issue where Adobe Send & Track uploads a PDF successfully but fails to send the corresponding email notification.

Fix Adobe Send & Track Uploads But Does Not Send Email

Product: Adobe Send & Track
Device & OS: not provided
Scenario: Sharing a PDF document via email using Adobe's Send & Track feature on a secure or restricted network.
Observed behavior: The PDF file appears to upload without any error messages, but the system does not generate or deliver the email to the recipient.

Before you start

Verify that your internet connection is stable and check if you are connected to a corporate network with strict firewall or proxy rules.

Solution 1Recommended

Check Firewall and Content Gateway Rules

Network security appliances like firewalls or proxy servers may block the specific background connection Adobe uses to trigger emails.

In many corporate environments, strict network security policies can interrupt cloud-based services. While the file upload port might be open, the background API request required to send the email notification might be blocked by a content gateway or proxy.

Access network settings

Open your firewall or network security software settings, or contact your IT department if you do not have administrative access.

Review network logs

Check the security logs to see if any outbound traffic to Adobe domains (such as *.adobe.com or *.acrobat.com) is being blocked or dropped.

Whitelist required domains

Add the required Adobe Send & Track domains and services to the allowed list (whitelist) in your proxy or content gateway configuration.

Restart and retry

Restart your Adobe application or refresh your browser, then attempt to upload and send the PDF file again.

Check Firewall and Content Gateway Rules

Corporate Networks: If you are on a company network, you will likely need to provide the exact error message and network details to your IT administrator or Adobe support to get the proper domains allowlisted.

Solution 2

Test on an Alternative Network or Browser

Isolating the issue to a specific network or browser can help determine if local restrictions are causing the failure.

Frequently Asked Questions

Why does my PDF upload but the email doesn't send?

This usually happens when a network firewall or content gateway allows the initial file upload to the cloud servers but blocks the subsequent API call required to trigger the email notification.

How do I know if my proxy is blocking Adobe Send & Track?

You can test this by connecting your device to a mobile hotspot or a different network without proxy restrictions. If the email sends successfully on the new network, your proxy or firewall is likely blocking it.

What domains need to be whitelisted for Adobe services to work?

Your IT administrator typically needs to allowlist *.adobe.com, *.acrobat.com, and specific Document Cloud IP ranges in the network's firewall and web filtering rules to ensure full functionality.

Can I manually share the link if the automatic email fails?

Yes. If the file uploaded successfully, you can usually generate a shareable link from your Document Cloud interface and paste it directly into your own email client to send to the recipient.
