Emails going to Junk Folder and Inbox

Has anyone had problems with getting some emails sent from their campaigns to their junk folder and some campaign emails sent to their inbox? I seem to have 2 campaigns that will send the emails straight to my inbox, but the other two campaigns are sent to my junk folder.

I’ve set up the DKIM records and a SPF record, but haven’t found what the fix to this could be. Is there some other configuration that I need to fix?

Thanks in advance.
