please re open Email

Hello chandrashekar288,

Thank you for using Apple Support Communities. You mentioned that you're getting prompted that your email storage is full. To confirm, is this for your iCloud email? If so, we highly recommend that you attempt to manage your iCloud storage and create additional space by deleting items. This resource can show you how you can manage your iCloud storage: Manage your iCloud storage - Apple Support

If you're using a third-party email account and not iCloud, usually all you have to do is delete emails to clear up space. However, steps might differ depending on the email provider you have. You can try to reach out to your email provider for help in managing your email storage.

Thank you for using Apple Support Communities. Take care.
