Mail from LingQ Support

I stopped receiving mails of English LingQs of the Day from LingQ Support for the reason I do not know. I just want to know how I start receiving them again so I can use it for vocabulary learning.(I checked the setup page but it seemed nothing was wrong.)

This is because an email sent to your address bounced, so you were unsubscribed. I’ve now resubscribed you so you will receive emails again starting tomorrow. If anyone else is having the same problem, please let us know.

Thank you very much !
