By default, the account owner is the individual who initially created the Mailjet account using their email address.
To modify the account owner, you'll need to update the email address associated with the account.
Navigate to your Account Settings page and click on 'Update Profile'.
You'll be directed to a new page with the option to change the existing owner's email address. Click on the 'Change Email' button.
Enter the new email address and re-enter your login password for security verification.
A confirmation email will be sent to your new email address.
At this point, you'll be automatically logged out of your account. It's crucial not to log back in until you've confirmed the changes in your email, as doing so will cancel the update.
Once you've confirmed the change via email, you can log back into your account using the new email address.
We also recommend updating your password for added security measures.
