An electronic signature is a legal and secure way for one or many people to sign a digital version of a document. Electronic signatures carry the same legal weight as wet ink signatures when completed through legitimate online services. eSignatures are secure, trusted worldwide and can often replace handwritten signatures.

In this article, we’ll discuss how to create an electronic signature that you can use to sign emails, contracts and documents online like you would in person.

How to Set up an eSignature to Sign Email Documents

A digital signature can add an extra layer of security to an email message by showing the recipient that you signed it, not someone else. Most email clients offer digital signatures in their applications. Outlook, for example, offers a sign feature in its permissions menu.

You can also use an online signature service, like jSign, to create an online signature. Once you have your electronic signature created, you can use it to legally sign emails to show that you are the one writing and responding to them. Here’s how:

  1. Register for a free jSign trial account and log in.

    1. Draw your electronic signature with a stylus or your finger right on a touch screen.
    2. Type your name into the document’s signature field.
    3. Upload an image of your signature to apply to documents.
    4. Use an external signature pad to add an electronic signature to your document.
  3. Once you have your eSignature, you can use it to sign your emails electronically.

  2. Upload a scanned or photographed image of your signature to apply to documents.
