How do you get POP3?
Your email provider is likely already providing it, but you have to configure that setting on your email client (Thunderbird/Outlook/etc.).
You can check with your provider to see if they have it available, then configure your client, as needed. It’s usually a radio button and a server name change in your local client.
Hotmail, Gmail, and about everyone else has that, but I have seen a fee cases where it was an added cost (Hushmail in the past).
