It’s easy as 1, 2, 3
Changing your email address is easy. Here’s how:

Tap on your profile picture
Tap Edit
Enter your email address in the Email box then tap on Save
If you need to use your current email for a different Showbie account, you can type in a fake email (for example, fakeemail@fakeemail.com) so that it frees up the email you need. You can then use the email for another Showbie account!
Next Steps
With your email address set up, you can change your notification settings so that you receive emails for all the important things you want to stay informed about. Learn more about Notifications Settings.
