Is there a way to have an Office JS Add-in autoload without the user having to click the add-in button in the ribbon toolbar?

For example, we have an add-in that auto adds a BCC email address. We would like the add-in to be able to automatically add the BCC email address w/o having to click the add-in button.

We did this with a VSTO plugin but could not find a way to do this using the new Add-In JS API.

Currently the feature to auto load office add-in outlook is not a part of the product. We track Outlook add-in feature requests on our user-voice page. Please add your request there. Feature requests on user-voice are considered when we go through our planning process.Outlook Add-ins Team - MSFT

  1. A web add-in can add support for ItemSend event (these add-ins are automatically opened in background, when the user clicks on send button) but have a look at limitations of ItemSend before taking that route.
  2. A web add-in can support pinning (if the user has pinned the add-in, next time the add-in automatically opens in task pane).

There is no other way to open a web add-in without user interaction. There is user voice, which is similar to your scenario, you can add your support to that.
