Here is a list of steps you can take if your emails are being sent from the wrong address:

1. Check your email settings and ensure that your primary email address is selected as your sending address
2. Check the rules in your email client to make sure you are not sending in the wrong address based on conditions in the rule
3. Make sure you are logged into the correct email account when sending emails
4. Verify that auto-replies and auto-copy are not set to the wrong address
5. Ensure that any third-party applications, such as MailChimp or SendGrid, are sending from the correct address
