Identifying the Symptom: Email Bounces

One common issue users encounter with Mailjet is email bounces. This occurs when an email cannot be delivered to the recipient's inbox. You might notice an increase in bounce rates, which can affect your email deliverability and sender reputation.

Exploring the Issue: MJ-027 Error Code

The MJ-027 error code is associated with email bounces. This typically happens when emails are sent to invalid or non-existent email addresses. Bounces can be categorized into two types: hard bounces and soft bounces. Hard bounces are permanent failures, while soft bounces are temporary issues that might resolve over time.

Hard Bounces

Hard bounces occur when the recipient's email address is invalid or does not exist. This can happen due to typos, outdated contact information, or domain issues.

Soft Bounces

Soft bounces are temporary delivery failures. They might occur due to a full inbox, server issues, or temporary network problems. Soft bounces can be retried after some time.

Steps to Resolve Email Bounces

To address the MJ-027 error and reduce email bounces, follow these actionable steps:

1. Monitor Bounce Reports

Regularly check your Mailjet bounce reports to identify problematic email addresses. You can access these reports through the Mailjet dashboard. For more details, visit the Mailjet API Documentation.

2. Remove Invalid Email Addresses

Once you've identified invalid email addresses, remove them from your contact list. This will help improve your sender reputation and reduce bounce rates. You can use the following command to remove an email address from your list:

DELETE /v3/REST/contact/{contact_ID}

Refer to the Mailjet Contact API for more information.

3. Validate Email Addresses

Implement email validation at the point of collection to ensure that only valid email addresses are added to your list. You can use third-party validation services or regular expressions to validate email formats.

4. Use Double Opt-In

Consider using a double opt-in process to confirm the validity of email addresses. This involves sending a confirmation email to new subscribers, ensuring that they have provided a valid and active email address.
