Our system automatically unsubscribes an email address from our mailing lists if three emails in a row are returned as undeliverable. We have now resubscribed you, but it would be worth investigating why the emails are bouncing.


The three most common reasons are:

  • An incorrect email address: Please log in to your Tutor account and check that the email address registered is correct.
  • A firewall or email filter: Some organisations need our sending email address to be added to their safe-senders list. You may need to ask your IT team or email provider to check this.
  • A full mailbox: If your inbox has reached its storage limit, you will need to delete some emails to free up space.


If the problem continues after you have checked these, please let us know.
