Does your email provider have a junk filter that you can enable? How about your email client (the app on your phone that you use the check the email)?
Other than paying for a filtering service, the above options are the only ones available to you. I would begin by logging into you email account on a computer (i.e., not your phone), and looking at your settings.
Thanks have done that contacted my provider closed and reopened my account hopefully that will work
