How to Fix Adobe Sign Email Missing the Link to Open Document
Question details
The user receives an Adobe Sign email requesting a signature, but the message lacks the necessary hyperlink to open and sign the PDF document.

- Product
- Adobe Sign / Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to access and sign a PDF document sent via email for electronic signature.
- Observed behavior
- The email arrives without a clickable link to view or sign the document, preventing the recipient from completing the signature workflow.
Verify that your email client or enterprise firewall is not stripping HTML content or blocking external URLs as a security precaution.
Verify the Sending Workflow and Email Settings
Determine how the document was sent and check for email filtering issues that might be removing the signature link.
Email security systems often strip links from incoming messages if they suspect phishing. Additionally, different Adobe tools use different mailing workflows which can affect how the link is delivered.
Look for a duplicate email or notification in your spam, junk, or enterprise quarantine folders. Strict email filters may alter the message content in your main inbox.
Ask the sender to confirm if they used the 'Fill & Sign' tool in Adobe Acrobat/Reader DC or an enterprise Adobe Acrobat Sign subscription, as the routing methods differ.
If the sender is using Adobe Acrobat Sign, ask them to log in, navigate to the 'Manage' tab, select your document, and manually copy the signing URL to send to you directly.
If the issue persists, request the sender to cancel the current transaction and initiate a new signature request using the correct workflow.

Sign PDF Documents Locally with WPS Office
Avoid complex email link issues by signing PDF documents directly within WPS Office. You can ask the sender to email you the raw PDF file, sign it locally using our comprehensive PDF editor, and send it back securely.
- 1. Open your PDF: Launch WPS Office and open the PDF document you need to sign.
- 2. Access the Signature Tool: Navigate to the 'Protect' or 'Insert' tab on the top ribbon and select 'Sign'.
- 3. Create Your Signature: Click 'Create Signature' to type your name, draw your signature, or import an image of your physical signature.
- 4. Apply and Save: Place the signature precisely where needed on the document, then save the file and reply to the sender with the signed attachment.

Frequently Asked Questions
Why would an email client remove the link from an Adobe Sign message?
Strict enterprise firewalls or email security software (like Proofpoint or Mimecast) may strip unverified URLs or quarantine HTML emails to prevent phishing, leaving only the plain text version of the email without the clickable signing link.
Does the Fill & Sign feature in Adobe Reader send emails differently than Adobe Sign?
Yes, the basic Fill & Sign tool in Acrobat/Reader DC uses a different, simpler email routing system compared to the enterprise Adobe Sign platform. This difference in server routing could explain why links might drop in one workflow but not the other.
What should I do if the document still cannot be signed via the web link?
If you cannot get the web link to work, ask the sender to download the PDF and attach it directly to a standard email. You can then sign it locally using PDF software like WPS Office before returning it as an attachment.
