Mailjet is a powerful email communication API provider that allows businesses to send, receive, and track emails effortlessly. It offers a range of features including email marketing, transactional emails, and analytics to help optimize communication strategies.
When using Mailjet's API, you might encounter an error message indicating an 'Invalid Contact List ID'. This error prevents emails from being sent to the intended recipients.
The error code MJ-023 signifies that the Contact List ID specified in your API request does not match any existing lists in your Mailjet account. This can occur due to a typo, an outdated ID, or an incorrect reference in your code.
Follow these steps to troubleshoot and resolve the MJ-023 error:
Log in to your Mailjet account and navigate to the Contact Lists section. Ensure that the ID you are using in your API call matches exactly with one of the existing lists.
Once you have verified the correct Contact List ID, update your API call to reflect this ID. Ensure that there are no extra spaces or incorrect characters in your code.
