Sorry to hear that you face this problem,to troubleshoot this problem first we would like to ask to check your spam folder, if your email provider tried to block LiteBit wallets.
If it is not possible to receive emails there are 2 alternatives.
- Replace your current email address with a new email address
- Activate two step verification (also improves security)
Two step verification
With using two step verification (2FA) instead of confirming emails you type in a 6 digit code.
Which will improve transaction time and less blocked emails from providers. More information in the following article:
