Duplicate Signatures on Email Sends

When a client or success rep reaches out and they state that there are multiple signatures on an email send, this is expected behavior. We include signature images as attachments then have them show in the body of the email. We do this so recipients are not prompted to download signature images, but they are shown automatically when the email is viewed.

Some email clients still show the attachment with other attachments while other clients do not. There is nothing we can do to control this unfortunately.
