I don't have specific information about notifications you receive when joining a workspace. However, I can share some related information about Clay's referral program.Clay has recently introduced in-platform referrals for all workspaces. Each workspace now has a unique referral link. When a new user signs up using this link and activates a paid account, both the referrer and the new user receive 3,000 credits for their respective workspaces.To better assist you with your specific question about notifications, could you please provide more details about the notification you're receiving? What does it say, and at what point during the joining process do you see it?
