The Dropbox Sign Add-On for Gmail allows users to sign attachments they receive directly from their gmail account. There are two different ways to install this add-on, the first being going directly to the G Suite Marketplace using this link and follow the prompts for install.
The second option is to install directly through your gmail account. Click on the gear icon on the right hand side, then click on See all settings -> Add Ons -> Manage.
From here search for 'Dropbox Sign' and follow the install prompts.
