Understanding Email Suppression Lists: Causes, Resolutions, and Prevention
Emails play a crucial role in communication, and any disruptions can be frustrating. One such issue is when an email address is added to the Horizon email suppression list. This article covers what suppression lists are, the reasons your email might be added to one, how to resolve the issue, and how to prevent it in the future.
What Is an Email Suppression List?
A suppression list is a system safeguard used to stop sending emails to addresses flagged for repeated delivery failures or rejections. When an email provider rejects emails to your address multiple times, the Horizon system automatically adds that address to the suppression list to avoid further issues. Once your email is on this list, emails from HorizonWebRef.com and associated services will cease to be delivered to your inbox. You will receive a notification in the Reminders Box on the Members Home page about this status, which may state that you've been placed on the AWS Email Suppression List. If you don't receive this explicit notification, then your email is likely not on the suppression list. Email addresses are only added to the suppression list after repeated failures or rejections.
Common Causes for Suppression
Your email might be added to the suppression list due to:
Email Rejections: Your email provider repeatedly rejects the messages sent due to settings, restrictions, or other issues.
Delivery Restrictions: Policies or filters on your account block or bounce messages.
Nonexistent Addresses: If the email address isn’t valid, it becomes undeliverable.
How to Resolve Suppression Issues
If your email address is added to the suppression list, here’s how to restore normal email flow:
Contact Your Provider: Work with your email provider to identify and address the root cause of the rejection or bounce. This may involve Removing specific blocks or filters, or adjusting settings that rejected these emails.
Address Removal: The Horizon support team can then remove your email from the suppression list to allow emails to resume. Contact support via our online chat messenger to speak with a human agent.
Prevention Strategies
To avoid future suppression, follow these best practices:
Whitelist Horizon WebRef Domains: Ensure your email provider allows messages from these domains: -
[horizonwebref.com](https://horizonwebref.com)-[horizonstaffscheduler.com](https://horizonstaffscheduler.com)-[amazonses.com](https://amazonses.com)Update Email Filters: Remove any restrictive filters or rules that might reject emails from Horizon.
Proactive Monitoring: Regularly check with your email provider to ensure your address is in good standing and no new restrictions are in place.
Final Considerations
Email suppression is a safeguard to ensure consistent and appropriate email delivery. While suppression lists might initially sound problematic, they are easy to address by understanding their causes, resolving the issues, and implementing preventive measures effectively. If the issue persists, consult with your email provider or HorizonWebRef.com support for further guidance.
