Understanding why an email address is blocked

There will unfortunately always be the risk of emails bouncing and becoming blocked in any system. The following article explains the difference between these two situations: Understanding Bounced / Blocked emails


Blocked emails are no longer available for sending, so we recommend you actively monitor blocked emails in the EnrolNow system. 


A blocked reason is shown in EnrolNow when you hover over the email address and/or in a seperate column when viewing blocked emails in bulk as described [here]. This reason indicates the likely fix. The most common reasons, and the recommended next step for each, are set out below.

  • The recipient has chosen not to receive emails from you
    This block occurs when a parent has unsubscribed from your emails (for example, by clicking an unsubscribe link in a previous email). When this happens, the Email Opt Out field on the parent's profile is automatically ticked, which prevents any further emails being sent to them.
    Next step: This one can be resolved directly in EnrolNow One:
    1. Navigate to the child's profile.
    2. Click on the impacted parent's name (this will take you to the parent's own profile page).
    3. Locate the Email Opt Out field, untick it, and then click the blue tick to the right to save the change.
    4. If the email address was only temporarily blocked due to the unsubscription, you should now be able to send to the parent again. If you still can't send to the family, please contact the EnrolNow Support Team and we'll provide further advice.
  • 5.1.1 – The email account does not exist
    Next step: Contact the family to check the email address and update it in EnrolNow One.

  • 5.7.1 – Rejected by spam filter
    Next step: Please discuss with EnrolNow whether there are opportunities for improved email integration that may help mitigate this issue. Once the underlying issue has been addressed, EnrolNow can request these emails be unblocked by Zoho.

  • 5.4.4 – DNS Error / Domain not found
    Next step: Check the email address — an easy correction may be available.

  • 4.2.2 – The email account you tried to reach is over quota
    Next step: Contact the family to advise that their email is showing as full, and check whether an alternative email account is available.

  • 5.2.2 – Mailbox full
    Next step: Contact the family to advise that their email is showing as full, and check whether an alternative email account is available.

  • 5.7.509 – Access denied; sending domain does not pass DMARC verification and has a DMARC policy of reject
    Next step: This means the email was sent from a domain (e.g. XXX.vic.gov.au) that failed DMARC verification, and the recipient's email system is rejecting it due to strict DMARC policy settings. Speak with your IT provider or domain administrator to ensure your domain has correct SPF, DKIM and DMARC records set up.
