If you have not yet received an email from Instagram, you need to be patient and wait for a few minutes. If you still have not received an email from Instagram in the last 10 minutes, you should check your internet connection. Additionally, you can also check other folders in your email pages, like promotions and the spam folder. Be sure to check into all potential folders of your email account. If you still did not find it, you may have to reset your spam filter, head back to Instagram, and put request a new email address.
