I checked. There isn’t any built-in way to do this right now. If you want to give it a try, the relevant flow for the e-mail is this:

[Rails controller sets cookie](https://github.com/discourse/discourse/blob/main/app/controllers/static_controller.rb#L131-L133)  
 → [Ember router reads cookie and passes value to Ember controller](https://github.com/discourse/discourse/blob/main/frontend/discourse/app/routes/signup.js#L96-L98)  
 → [Ember component accesses value on Ember controller](https://github.com/discourse/discourse/blob/main/frontend/discourse/app/templates/signup.gjs#L75)

Could also be worth checking with the team if they’d accept a PR for this, before making it a plugin.
