Mailjet Emails are not being delivered to certain recipients.

The recipient's email address is on the suppression list.

Understanding Mailjet: A Powerful Email Communication API

Mailjet is a robust email communication platform designed to help businesses send, track, and deliver emails effectively. It provides a comprehensive suite of APIs that enable developers to integrate email functionalities into their applications seamlessly. With Mailjet, you can manage transactional emails, marketing campaigns, and more, ensuring reliable and efficient email delivery.

Identifying the Symptom: Blocked Email Address

One common issue encountered by Mailjet users is the non-delivery of emails to specific recipients. This symptom is often observed when emails are not reaching their intended destinations, leading to communication breakdowns and potential business disruptions.

Exploring the Issue: Error Code MJ-005

The error code MJ-005 indicates that the recipient's email address is blocked due to being on the suppression list. Mailjet maintains a suppression list to prevent emails from being sent to addresses that have previously resulted in bounces, spam complaints, or unsubscribes. This is a protective measure to maintain sender reputation and ensure compliance with email regulations.

Understanding Suppression Lists

Suppression lists are crucial for maintaining email hygiene. They help in avoiding sending emails to addresses that are likely to result in delivery failures. However, sometimes legitimate addresses may end up on this list due to temporary issues or errors.

Steps to Fix the Issue: Removing an Email from the Suppression List

To resolve the MJ-005 error and ensure emails are delivered to the intended recipient, follow these steps:

Step 1: Access Your Mailjet Account

Log in to your Mailjet account. If you don't have an account, you can sign up here.

Step 2: Navigate to the Suppression List

Once logged in, go to the 'Contacts' section in the Mailjet dashboard. From there, select 'Suppression List' to view all the email addresses currently blocked.

Step 3: Search for the Blocked Email Address

Use the search functionality to find the specific email address that is experiencing delivery issues. Verify that it is indeed on the suppression list.

Step 4: Remove the Email Address

If the email address is on the list and you have verified that it should not be blocked, select the address and choose the option to remove it from the suppression list. This action will allow future emails to be delivered to this address.

Additional Resources

For more detailed guidance on managing suppression lists and improving email deliverability, refer to Mailjet's official documentation. Additionally, you can explore best practices for email deliverability in Mailjet's blog.

By following these steps, you can effectively resolve the MJ-005 error and ensure your emails reach their intended recipients without unnecessary blocks.
