Mailjet Duplicate emails being sent to the same contact.

Duplicate Contacts in the Mailjet contact list.

Understanding Mailjet: A Powerful Email Communication API

Mailjet is a robust email communication API provider that enables businesses to send, receive, and track emails effortlessly. It is widely used for transactional and marketing emails, offering features like email automation, contact management, and analytics.

Identifying the Symptom: Duplicate Emails

One common issue users encounter is the sending of duplicate emails to the same contact. This can lead to customer dissatisfaction and potential spam complaints, affecting your email deliverability and reputation.

Exploring the Issue: Error Code MJ-014

The error code MJ-014 indicates the presence of duplicate contacts in your Mailjet contact list. This duplication causes multiple emails to be sent to the same address, which is not only inefficient but can also harm your sender reputation.

Root Cause: Duplicate Contacts

Duplicate contacts often occur due to multiple imports of contact lists or errors during data entry. Identifying and removing these duplicates is crucial to maintaining a clean and efficient contact list.

Steps to Resolve the Issue

Step 1: Access Your Mailjet Account

Log in to your Mailjet account and navigate to the Contacts section. Here, you can manage your contact lists and identify duplicates.

Step 2: Identify Duplicate Contacts

Use Mailjet's built-in tools to search for duplicate contacts. You can do this by exporting your contact list and using spreadsheet software to find duplicates based on email addresses.

Step 3: Remove Duplicate Entries

Once duplicates are identified, remove them from your contact list. This can be done manually or by using Mailjet's API to automate the process. Refer to the Mailjet API documentation for more details on automating contact management.

Step 4: Verify and Test

After cleaning your contact list, send a test email to ensure that duplicates have been removed and emails are being sent correctly. Monitor your email logs for any anomalies.

Conclusion

By following these steps, you can effectively resolve the MJ-014 error and prevent duplicate emails from being sent. Maintaining a clean contact list is essential for optimal email performance and customer satisfaction. For further assistance, visit Mailjet's support page.
