What is Cloudmark?
Cloudmark is a robust spam filtering system that helps protect email users from unwanted and potentially harmful messages. Unlike Google or Microsoft mailboxes, Cloudmark operates independently and enforces stricter criteria to identify and block spam. This enhanced filtering is beneficial for maintaining a clean inbox but can sometimes lead to legitimate emails being bounced if they are flagged as spam.
Why Are My Emails Bouncing?
If you receive a bounce message indicating that your email was rejected by Cloudmark, it typically means that your email content triggered Cloudmark's spam filters. This can happen for several reasons:
Spam Complaints: If recipients have previously marked emails from your domain as spam, Cloudmark may block your future emails.
Bad Cold Email Copy: Emails that contain elements commonly associated with spam, such as certain phrases, links, or attachments, are more likely to be flagged and bounced.
How to Address and Prevent Cloudmark Bounces
If your emails are being consistently bounced by Cloudmark, you can take action to reset your reputation. Follow these steps:
Visit the Cloudmark Reputation Reset Form: Go to Cloudmark Reputation Reset Form.
Fill Out the Form: Provide the necessary details about your domain and the issue you are experiencing. You can get your IP address from the server tab within Mailreef.
Submit the Form: Once submitted, Cloudmark will review your request and take appropriate action to reset your reputation.
Impact on Deliverability
It’s important to note that Cloudmark typically affects only a small percentage of emails, particularly those sent to users who do not have Google or Microsoft mailboxes. As a result, while Cloudmark bounces can be frustrating, they are unlikely to significantly impact your overall email deliverability. By following the steps outlined above, you can minimize the chances of your emails being flagged and ensure they reach your intended audience.
