Is there a way to have one subscription for 3 different Trello accounts? I use 3 different emails

I want to be able to pay for premium at a one time cost. I use trello for 3 different brands with 3 different emails. Is it possible to pay for 1 subscription?

Isn't that like going to the shop and saying, "I want 3 apples but I only want to pay for 1" 😁

Seriously though, I would suggest having 1 Trello workspace, 1 Trello account tied to a single central email address.  Apart from receiving emails from Trello, the email address you've signed up with is rather insignificant once you're signed up.   If you're reliant on Trello emails for notifications, try using the Trello notification system or create automations to send emails to the necessary brand email addresses
