The HelloSign for Gmail plugin allows a user to open, edit and sign documents in Gmail and automatically loads the signed and edited document as an attachment to be sent. It is now only available in Chrome but will be added as a plugin to Firefox. It is not available in Internet Explorer or the Safari browser.
All signed documents are legally binding and automatically backed up in the user’s HelloSign account with other documents.
Adding the Chrome extension is pretty simple. In its tutorial, HelloSign takes the user through the process. It shows how a contract appears. There are three options for the file: view, download or sign. A signature box appears where you can type your name.
Here’s another look at the service:
DocuSign is the giant in the electronic signature market. It does not directly provide a way to sign documents and instead integrates with Zapier for people to create the signing app themselves.
I know I would not create my own app to sign documents in Gmail when there is something as easy to use as HelloSign.
