How are you accessing your email (and with what type of device)? Also which email provider are you using (i.e. the bit after @ in your email address?)
We need to know:
(a) whether you're using a PC, an Android device or something else ;
(b) whether you're using an email client (such as Outlook Express, Windows Live Mail or Thunderbird), a dedicated email app (on your phone or elsewhere) or simply going to your service provider's website (via a web browser, such as Internet Explorer, Edge, Firefox, Chrome, Safari or Opera).
