Stop sending me emails meant for other people

You allowed someone to use my email address, now I am getting these daunting "Mmakobedi Nkoana has invited you to be pre-approved for a home loan", emails when I do not even know who these people and why you people could not verify your clients' email addresses. This is horribly annoying. Vet your clients and verify that every piece of information that your clients give to you is correct and valid. Now I have to keep deleting emails because you people cannot stop sending me these nonsensical emails that are not meant for me. Can someone stop these people from sending me emails
