How to Create a Fillable and Signable PDF to Email Without Adobe Sign
Question details
The user needs to create a contract PDF with fillable date and signature fields that can be sent via standard email, completely independent of Adobe Sign routing.

- Product
- PDF Editor
- Device & OS
- not provided
- Scenario
- Preparing a contract document to be manually emailed to a client, requiring the client to fill in the date and securely sign the document before emailing it back.
- Observed behavior
- Standard text fields accept typed text but do not integrate properly with native Fill & Sign tools for capturing an actual signature.
Ensure you have a desktop PDF editing application capable of creating interactive form fields, such as Adobe Acrobat Pro or WPS Office, as free PDF readers cannot insert new form fields.
Add Digital Signature Fields Using Acrobat Pro
Use the 'Prepare a Form' tool to insert dedicated digital signature fields that allow clients to sign independently on their end.
To allow a client to sign a document natively without using third-party routing services, you must use a dedicated Digital Signature field rather than a standard text field. Digital signature fields trigger the certificate-based signing workflow in standard PDF readers.
Launch Acrobat Pro, open your contract document, and select 'Prepare a Form' from the right-hand tools pane.
Click the 'Add a Text Field' icon in the top toolbar and drag it onto the document where the date should appear. You can adjust the properties to restrict the format to dates if desired.
Select the 'Add a Digital Signature Field' icon (usually depicted as a pen with a signature line) and draw a box at the bottom of the contract. This designates the exact area where the client's signature certificate will appear.
Save the updated PDF form to your computer. You can now open your normal email client, attach the saved PDF, and send it directly to your client.

Create Fillable PDF Forms Easily with WPS Office
WPS Office offers comprehensive PDF editing tools that allow you to seamlessly insert text fields, checkboxes, and interactive signature fields. You can prepare professional forms and email them independently without relying on expensive enterprise routing services.
- 1. Open Your Document: Launch WPS Office and open your existing contract or document in the PDF editor.
- 2. Access Form Tools: Navigate to the 'Form' tab on the top ribbon to reveal the interactive field options.
- 3. Add Text and Signature Fields: Click 'Text Field' to add fillable spaces for the date or client name, then click 'Signature Field' to designate the signing area.
- 4. Save and Send: Save the finalized interactive PDF to your local drive and attach it to your standard email client to send to the recipient.

Frequently Asked Questions
Why can't my client use the Fill & Sign tool on the text field I created?
Standard interactive text fields are programmed to strictly accept typed characters from a keyboard. The native 'Fill & Sign' tool (which stamps drawn or image-based signatures) cannot drop elements inside an active text field. To fix this, you must use a specific Digital Signature field or leave the space entirely blank.
Do I need a paid subscription to Adobe Sign to email a document for signatures?
No. Adobe Sign is a cloud-based routing service that automates document tracking. If you manually add a Digital Signature field to your PDF, save it, and attach it to a standard email, the recipient can sign it locally for free and reply to your email with the signed attachment.
Can clients sign a PDF with a digital signature field if they only have a free reader?
Yes. Most modern free PDF readers, including Adobe Acrobat Reader and WPS Office, fully support filling in text fields and interacting with digital signature blocks using a self-signed or pre-configured digital ID.
How do I prevent the client from modifying the original contract text?
Before emailing the document, you can apply document restrictions. Go to the security or protection tab in your PDF editor (like Acrobat Pro or WPS Office) and set a permissions password to restrict editing, while ensuring that the 'Filling in form fields and signing' option remains allowed.
