2 Alternative Methods of Requesting a Signature on a PDF
Many businesses and individuals rely on two alternative methods for signing PDFs, i.e., built-in e-signature features or simple email workflows. While these work, they often involve extra steps or software requirements that can slow down the signing process.
That said, let’s examine both methods in more detail.
#1. Using Built-in E-Signature Features
Many PDF editors, such as Adobe Acrobat, include built-in e-signature tools that allow you to send documents for signature directly from the software. Typically, you upload or open a PDF, add signature fields, enter the recipient's email address, and send the request.
This can be convenient if you already use the software regularly and need advanced document management features. However, some capabilities may require a subscription, and recipients may need to navigate a specific signing platform. For organizations handling large volumes of documents, managing multiple requests can become more complex.
#2.Sending a PDF via Email for Manual Signature
Another approach is to email the PDF directly to the recipient and ask them to sign it. Depending on the recipient's setup, they may print the document, sign it by hand, scan it, and email it back. Others may add a digital signature using a PDF editor.
While this method is simple and doesn’t require specialized software, it can be time-consuming as multiple email exchanges can create delays. Also, limited visibility into whether the document has been received, opened, or completed makes it less efficient for contracts, approvals, and other time-sensitive documents.
Is It Safe to Request a Signature on a PDF Online?
Yes, requesting a signature on a PDF online is generally safe when you use a reputable platform. Most trusted services protect documents with encryption, secure data transmission, access controls, and audit trails that record when a document is sent, viewed, and signed.
However, online signature requests are not completely risk-free. Attackers may impersonate legitimate companies to trick recipients into revealing sensitive data or login credentials. The scale of this threat is underscored by the FBI’s 2024 Internet Crime Report, which recorded over 859,000 cybercrime complaints.
7 Best Practices for Requesting PDF Signatures
Before sending a PDF for signature, follow these seven best practices to protect sensitive information:
#1. Keep Documents Clear and Final Before Sending
Sending a PDF that still needs edits can lead to confusion, delays, and multiple signing requests. Recipients may sign an outdated version, forcing you to restart the process. Before sending, review the document and ensure all terms, dates, and attachments are finalized.
Tip: Create a checklist and confirm all stakeholders have approved the document before requesting signatures.
#2. Double-Check Recipient Emails
A simple typo in an email address can send confidential documents to the wrong person or prevent the intended signer from receiving the request. This can create delays and, in some cases, expose sensitive information. Always verify recipient email addresses before sending signature requests, especially for contracts, financial documents, and legal agreements.
Tip: Copy email addresses directly from trusted records instead of entering them manually whenever possible.
#3. Add Clear Instructions for Signers
If instructions are unclear, signers may miss required fields, sign incorrectly, or abandon the process altogether. Briefly explain what the document is, where signatures are required, and whether there is a deadline for completion.
Tip: Include a short message outlining the purpose of the document and the exact actions the signer needs to take.
#4. Protect Sensitive Information
Many documents contain personal, financial, legal, or business information. Sharing these files without proper safeguards can increase the risk of data breaches. Review documents carefully and remove unnecessary sensitive information before sending.
Tip: Use password protection, access controls, or authentication features when handling confidential documents.
#5. Verify Requests to Prevent Scams
Cybercriminals often use fake documents and signature requests to steal information. Recipients may receive emails that appear legitimate but direct them to fraudulent websites. Before signing or sending important documents, verify the sender and inspect links carefully.
Tip: Confirm unexpected signature requests through a separate communication channel before opening links or providing information.
#6. Use Secure Internet Connections
Public Wi-Fi networks in airports, hotels, cafes, and other shared spaces may expose sensitive information to security risks if they are not properly secured. This can be especially concerning when handling financial documents or files containing personal information.
Tip: Send and sign documents on a trusted private network, and avoid using public Wi-Fi when handling sensitive files.
#7. Set Clear Signing Deadlines
Signature requests without deadlines can easily get buried in a busy inbox. Recipients are more likely to complete requests when they understand the expected timeframe. This way you prevent important documents from remaining incomplete indefinitely.
Tip: Include a specific due date in your signature request and send reminders before the deadline if the document has not been signed.
