1. Use a Signing Service

Sometimes, the person who emails you makes the process incredibly easy. They might use a special business service like DocuSign, PandaDoc, or Adobe Sign. When they do this, you do not get a normal file attached to your email. Instead, you get a secure web link. This is the fastest way to electronically sign a document sent by email.

Here is how you complete it:

• Open the email in your inbox. Look for a big, colorful button that usually says "Review Document" or "Click Here to Sign". Click that button.

• The document will automatically open in your web browser (like Chrome or Safari). Read the document carefully.
• Look for a highlighted box on the page that says "Sign Here" and click on it.

• The website will ask you to draw your name using your computer mouse, or you can simply type your name using your keyboard.
• Once your name is on the page, click the "Finish" or "Submit" button. The website will automatically lock the document and send the signed paper back to the sender. You do not even need to write a reply email!

2. Use SwifDoo PDF

3. Use Adobe Acrobat

• Download the PDF attachment from your email and save it to your computer. Open the file using Adobe Acrobat.
• Look at the long menu on the right side of your screen. Find the signing tool and select “Add Signature.”

• A small box will pop open on your screen. Here, you can choose to either type your name or draw it with your mouse.

• Click anywhere on the document to place your name on the line. Remember to click "File" and then "Save" before you attach this finished file to your email reply.

4. Use a Browser (like Microsoft Edge)

What if you are in a big rush and you do not want to download or install any new software? You can actually learn how to sign a document sent by email for free using the web browser that is already on your computer. If you have a Windows computer, you can use Microsoft Edge. It has a very handy drawing tool built right into it.

Here are the easy steps to add a signature to a PDF in Microsoft Edge:

• Download the PDF document from your email and save it to a folder on your computer.
• Right-click on the file you just saved. A menu will appear. Move your mouse down to "Open with", and then choose "Microsoft Edge" from the list.
• The document will open up looking just like a normal webpage. Look at the top menu bar. Click the "Draw" button (the icon looks like a small pen pointing down).

• Your mouse cursor will turn into a pen. Hold down your left mouse button and use your mouse to draw your name directly on the signature line.
• When you are finished, click the "Save" icon in the top right corner, which looks like a small floppy disk. Now, you can open your email, hit reply, and attach this newly saved file.
