Very rarely teachable will have an issue delivering the login information for your purchase, this doesn't mean you aren't able to log in if your purchase went through, you'll just need to set up a new password manually.
1. To do so please visit: https://sso.teachable.com/secure/56863/users/password/new
2. and insert the email you purchased with.
If it says that your account is not found please submit a support ticket and we'll fix you right up!
