Your workplace gave you SNAEB

Your coffee is already paid for. You don't need to buy anything.

Find the email from SNAEB called “You've been invited to SNAEB”. Check spam too.
Tap the link in it, and create your account with the same email address.
That's it: you're on your company's plan and can get a coffee today.
